Novel Porous Crystals with Macrocycle-Based Well-Defined Molecular Recognition Sites

ConspectusMolecular recognition is one of the fundamental events in biological systems, as typified by enzymes that enable highly efficient and selective catalytic reactions through precise recognition of substrate(s) and cofactor(s) in the binding pockets. Chemists therefore have long been inspired by such excellent molecular systems to develop various synthetic receptors with well-defined binding sites. Their effort is currently being devoted to the construction of not only molecular receptors but also self-assembled host compounds possessing connected cavities (pores) in the crystalline frameworks to rationally design functional porous materials capable of efficiently adsorbing molecules or ions at binding sites on the pore walls. However, it is still challenging to design multiple distinct binding sites that are precisely arranged in an identical framework, which is currently one of the most important targets in this field to realize elaborate molecular systems beyond natural enzymes.In this Account, we provide an overview of porous crystals with well-defined molecular recognition sites. We first show several strategies for arranging macrocyclic binding sites in crystalline frameworks such as metal-organic frameworks, porous molecular crystals, and covalent organic frameworks. Porous metal-macrocycle frameworks (MMFs) that we have recently developed are then described as a new type of porous crystals with well-defined multiple distinct binding sites. The MMF-1 crystal, which was developed first and is composed of four stereoisomers of helical PdII 3-macrocycle complexes, has one-dimensional channels with dimensions of 1.4 nm ¡Á 1.9 nm equipped with enantiomeric pairs of five distinct binding sites. This structural feature of MMF-1 therefore allows for site-selective and asymmetric arrangement of not only single but also multiple guest molecules in the crystalline channels based on molecular recognition between the guests and the multiple binding sites. This characteristic was also exploited to develop a heterogeneous catalyst by non-covalently immobilizing an organic acid on the pore surface of MMF-1 to conduct size-specific catalytic reactions. In addition, adsorption of a photoreactive substrate in MMF was found to switch the photoreaction pathway to cause another reaction with the aid of photoactivated PdII centers arranged on the pore walls. Furthermore, the dynamic, transient process of molecular arrangement incorporated in MMF-1 has been successfully visualized by single-crystal X-ray diffraction analysis. The formation of homochiral MMF-2 composed of only (P)-or (M)-helical PdII 3-macrocycle complexes is also described. Thus, macrocycle-based porous crystals with a complex structure such as MMFs are expected to serve as novel porous materials that have great potential to mimic or surpass enzymes by utilizing well-defined multiple binding sites capable of spatially arranging a catalyst, substrate, and effector for highly selective and allosterically tunable catalytic reactions, which can be also visualized by crystallographic analysis because of their crystalline nature.

Amperometric Detection of dsDNA Using an Acridine-Orange-Modified Glucose Oxidase

In the present ?genomic era? and in the developing world of DNA chips, DNA detection based on intercalation of specific molecules is of particular interest because the detection process is largely independent of the sequence of the target DNA. In this work, an acridine-orange-based intercalation compound, which was tethered to deglycosylated glucose oxidase was synthesized ad hoc and investigated for its ability to interact with dsDNA. Amperometric detection of DNA hybridization was achieved by signal amplification based on the catalytic oxidation of glucose by DNA-bound glucose oxidase. A clear distinction between dsDNA and ssDNA was achieved by careful design of a DNA-modified electrode surface and prevention of nonspecific adsorption of the acridine-orange-modified enzyme by implementing a potential-assisted immobilization method.

Organometallic amphiphiles: Oxidized ferrocene as headgroup for redox-switched bilayer and monolayer membranes

A family of 15 ferrocene derivatives has been prepared, most of which are reported for the first time. This includes FcCH2O-3-cholestanyl, 1; FcCH2O(CH2)13CH3, 2; FcCH2O(CH2)15CH3, 3; FcCH2O(CH2)17CH3, 4; FcCH2N[(CH2)17CH3]2, 5; FcCH2O(CH2)8OCH2Fc, 6; FcCH2O(CH2)12OCH2Fc, 7; FcCH2O(CH2)16OCH2Fc, 8; Fc(CH2)22Fc, 9; FcCH2-3,17-beta-estradioxy-CH2Fc, 10; Fc-1,1′-[COO(CH2)16CH3], 11; FcCONH(CH2)17CH3, 12; Fc-1,1′-{CON[(CH2)17CH3]2}2, 13; Fc-1,1′-(COO-3-dihydrocholesteryl), 14; and Fc-1,1′-(COO-3-cholesteryl), 15. Redox potentials for 1-15 have been determined and are in the range 400-450 mV for 2-6 (vs SSCE) and 509 mV for 1, 972 mV for 7, 806 mV for 8, 711 mV for 9, 941 mV for 10, and 945 mV for 11 (vs Ag/AgCl). Upon oxidation with Ce(IV), aqueous suspensions of compounds 1-5 and 7-10 formed stable vesicles after sonication. The charged monomers that formed vesicles afforded aggregates in the 2000-3000 A range that were characterized by laser light scattering and negative stain electron microscopy. In the absence of an oxidizing agent, vesicles failed to form from any of the 15 monomers even after prolonged sonication. Addition of 500 muM aqueous Na2S2O4 solution collapsed the vesicles formed from 1-5 and 7-10, and the original amphiphile monomers were detected afterward by thin layer chromatography. It was concluded from cyclic voltammetry that both ferrocene residues in 8 were oxidized. Vesicles formed from 7-10 represent the first examples of a redox-switched bolaamphiphile.

Label-free physical and electrochemical imaging of latent fingerprints by water and SECM

A label-free method that can doubly image both the physical patterns and the electrochemical information of latent fingerprints (LFPs) on nitrocellulose (NC) membrane has been achieved here by water and scanning electrochemical microscopy (SECM). In this approach, the NC membrane with LFP (LFP/NC) sample was first placed in water, where the different absorption of water onto relatively hydrophobic ridge residues of LFP versus NC membrane background resulted in a high-resolution physical ridge pattern of the fingerprint to naked eyes within just 1?3 s and could further be photographed by a digital camera. Thereafter, the LFP/NC sample was electrochemically imaged by recording the current variations of SECM tip scanning over the label-free fingerprint in the surface-interrogation (SI) mode. The methyl viologen (MV2+) was chosen as the redox mediator to react selectively with the electroactive species in the fingerprint ridge residues rather than furrow regions, which could cause the sharp contrast of the SECM tip current for imaging. Both the collected physical and electrochemical images of LFPs can provide high resolution up to level 2 and level 3 features required for personal identification. In addition, for the first time commercial NC membrane instead of adhesive forensic tape was discovered here for lifting the LFPs from various surfaces, which can then be imaged by this electrochemical approach. Taken together, this method demonstrates a powerful strategy for directly imaging the electrochemical information in LFPs without damaging the fingerprint physical ridge pattern on various substrates, so it has great potentiality in individual identity related applications.

Improvement of the corrosion resistance of biomedical zr-ti alloys using a thermal oxidation treatment

Binary Zr-Ti alloys spontaneously develop a tenacious and compact oxide layer when their fresh surface is exposed either to air or to aqueous environments. Electrochemical impedance spectroscopy (EIS) analysis of Zr-45Ti, Zr-25Ti, and Zr-5Ti exposed to simulated physiological solutions at 37 C evidences the formation of a non-sealing bilayer oxide film that accounts for the corrosion resistance of the materials. Unfortunately, these oxide layers may undergo breakdown and stable pitting corrosion regimes at anodic potentials within the range of those experienced in the human body under stress and surgical conditions. Improved corrosion resistance has been achieved by prior treatment of these alloys using thermal oxidation in air. EIS was employed to measure the corrosion resistance of the Zr-Ti alloys in simulated physiological solutions of a wide pH range (namely 3 ? pH ? 8) at 37 C, and the best results were obtained for the alloys pre-treated at 500 C. The formation of the passivating oxide layers in simulated physiological solution was monitored in situ using scanning electrochemical microscopy (SECM), finding a transition from an electrochemically active surface, characteristic of the bare metal, to the heterogeneous formation of oxide layers behaving as insulating surfaces towards electron transfer reactions.

Continuous assembly of supramolecular polyamine-phosphate networks on surfaces: Preparation and permeability properties of nanofilms

Supramolecular self-assembly of molecular building blocks represents a powerful “nanoarchitectonic” tool to create new functional materials with molecular-level feature control. Here, we propose a simple method to create tunable phosphate/polyamine-based films on surfaces by successive assembly of poly(allylamine hydrochloride) (PAH)/phosphate anions (Pi) supramolecular networks. The growth of the films showed a great linearity and regularity with the number of steps. The coating thickness can be easily modulated by the bulk concentration of PAH and the deposition cycles. The PAH/Pi networks showed chemical stability between pH 4 and 10. The transport properties of the surface assemblies formed from different deposition cycles were evaluated electrochemically by using different redox probes in aqueous solution. The results revealed that either highly permeable films or efficient anion transport selectivity can be created by simply varying the concentration of PAH. This experimental evidence indicates that this new strategy of supramolecular self-assembly can be useful for the rational construction of single polyelectrolyte nanoarchitectures with multiple functionalities.
