“…The present success in the anion-imprinted electropolymerization results from the rigid arene-based skeleton to preserve the cavity structure as the recognition site. Similar anion-controlled redox processes were also experienced in a conducting polypyrrole film . The rigid arene-based structure of the conjugated polymer would fabricate a kind of anion-imprinted crevice structure between the polymer chains.…”

The highly selective recognition of halide ions by a cross-linked polyviologen film was demonstrated electrochemically. The film was prepared on an electrode by electropolymerization of a branched monomer with three polymerizable groups, 1,3,5-tris(4′-cyanopyridinio-1′-methyl)-2,4,6-trimethylbenzene tribromide, to form a highly cross-linked polyviologen, through successive reductive coupling of the cyanopyridinium moieties. The highly cross-linked structure is built up by the formed viologen skeleton, incorporating the electrolyte anion used as the template to fabricate a kind of cavity structure complementary in size to the electrolyte anion, called anion-imprinted electropolymerization. The resulting cross-linked polyviologen film exhibits highly selective anion recognition in the redox process. The anion-controlled redox process was investigated quantitatively by multilateral analyses with cyclic voltammetry, potential-step chronoamperometry, and electrochemical quartz crystal microbalance measurement coupled with visible absorption spectrophotometry. A highly selective size exclusion effect by the cavity structure fabricated in the anionimprinted electropolymerization was demonstrated in the redox process of the viologen moiety in different kinds of aqueous electrolytic solutions. From the systematic study of the anion size recognition using a series of halide ions, not only the precisely fabricated cavity structure but also the anion diffusion dynamics in the cavities successfully running are suggested.

“…The average counterion composition, understood as the polymer/counterion ratio, inside the film increases continuously during oxidation by flow of a constant anodic current or by anodic potential sweep, giving, as average, a nonstoichiometric material [40,41]. This effect has been widely observed and was found to be dependent on the counterion molecular weight [63][64][65][66][67][68][69][70][71][72][73].…”

Science is one of the most robust conceptual constructs developed by human beings. Theoretical physical models have been developed involving the smallest and the largest systems over the full scale of the universe. At either extreme, the models, which provide for constant interaction forces between their components, describe experimental observations and are predictive.Life evolved from systems of intermediate size in relation to the extremes of universal scale. Life, biological organs, and cells develop functions only under chemical driving conditions. Natural organs can be considered as biological devices that are very efficient in transforming chemical energy at constant temperature into functions, unlike servitude of machines to the Carnot cycle. Inside any living cell, thousands of simultaneous reactions occur. Every reaction promotes changes from reactants to products, with subsequent changes to hundreds of intramolecular and intermolecular interactions. Moreover, most of those reactions link conformational changes of biopolymers with ionic and electronic movement driving water flow. Hence, many simultaneous chemical reactions, intermolecular, and intramolecular interactions involving conformational movements are outside the possibilities of current theoretical models. Theoretical descriptions of any living cell and predictions of its behavior when unhealthy are unavailable within our scientific models. This constitutes the proximity paradox [1] because we have been able to develop good and predictive theoretical models for subatomic or galactic systems, far removed from our everyday surroundings.Actuation of natural organs such as muscles involves, moreover, the chemical reaction of ATP hydrolysis simultaneous with sensing processes that provide living creatures with a perfect consciousness of both the characteristics of their mechanical movements and their interactions with their environment: they are intelligent machines.Most of our technological developments were inspired by biological functions and organs. One of our aims is to overcome the efficiency of the biological Electropolymerization: Concepts, Materials and Applications. Edited by Serge Cosnier and Arkady Karyakin

“…A suitable substitution of neutral ligands with anionic functional groups for example can turn neutral or even cationic complexes into anions. Thus, sulfonated ligands were used for instance for the integration of the metal phthalocyanine complexes mentioned above or iron trisphenantroline sulphonic acid complexes [201] into COPs.…”

Hybrid Organic-Inorganic Materials—In Search of Synergic Activity

This review surveys the work developed in the field of functional hybrid materials, especially those containing conducting organic polymers (COPs), in combination with a variety of inorganic species, from molecular to extended phases, including clusters and nano‐sized inorganic particles. Depending on the dominating structural matrix, we distinguish and analyze organic–inorganic (OI) hybrids, nanocomposite materials, and inorganic–organic (IO) phases. These materials have been used in a wide variety of applications, including energy‐storage applications, electrocatalysis, the harnessing of electrochromic and photoelectrochromic properties, application in display devices, photovoltaics, and novel energy‐conversion systems, proton‐pump electrodes, sensors, or chemiresistive detectors, which work as artificial “noses”.
