“…[215] On the other hand, concerning energy-storage applications, materials for supercapacitors [211] as well as for insertion electrodes in rechargeable lithium batteries [221,257,267] have been developed. Examples of other applications include the harnessing of electrochromic, [86,139,230,232] and photoelectrochromic [241] properties, application in display devices, [241] photovoltaics, [229] and novel energy-conversion systems, [227] proton-pump electrodes, [203] sensors, [32] or chemiresistive detectors, which work as artificial ªnosesº and already outperform human olfaction in detecting, for example, biogenic amines. [216] The applications of hybrid materials are promising and varied but in addition to improved devices, hybrid compounds are also interesting from a fundamental point of view.…”

REVIEWThis 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 ªnosesº.

“…For instance, the electrochromic properties of aromatically conjugated polyanilines [16][17][18][19][20] and their composites (e.g., polyaniline/cellulose acetate, 21 polyaniline/CdS, 22 and polyaniline/nitrilic rubber 23,24 ) have been reported. Heterocyclic polythiophene and its derivatives have also attracted much attention in academic research due to the recent discovery that polythiophenes with long alkyl chain substituents at the 3-position of the thiophene rings exhibit good solubility in common organic solvents in doped/undoped forms.…”

In this paper, a series of organic-inorganic hybrid materials, consisting of heterocyclic conjugated poly(3-hexylthiophene), P3HT, network, and silica particles, were successfully prepared for electrochromic studies. First, the heterocyclic co-polymer of poly[3-hexylthiophene-co-N-(3-trimethoxysilylpropyl) pyrrole], P(3HT-co-3TPP), containing trimethoxysilyl functional groups in the co-polymer backbone as the sol-gel precursor were prepared by conventional oxidative polymerization. Subsequently, P(3HT-co-3TPP)-silica hybrid sol-gel materials in the form of coatings were prepared by baking the microslides and ITO-coated electrodes that had been cast with homogeneous blending solutions containing co-polymer, acid-dopant, tetraethyl orthosilicate (TEOS), and a few drops of water. The microstructures of silica particles formed in the P(3HT-co-3TPP)-silica hybrid materials were investigated by transmission electron microscopy (TEM). The as-prepared hybrid coatings had improved adhesion capability on inorganic glass substrates relative to the pure P3HT on the basis of electrochemical cyclic voltammetric studies and Scotch tape test evaluations. During potential cycling, the film color of P(3HT-co-3TPP)-silica hybrid materials and P3HT coated on ITO electrode changed from orange yellow (i.e., reduced form) to dark blue (i.e., oxidized form) as the redox reactions proceeded. Effects of the material composition of P3HT along with hybrid materials on the electrochemistry, spectroelectrochemistry, thermal stability, and electrical conductivity were also studied.
