“…27 These polymers showed light blue emission in THF, whereas in the solvent mixture THF/H 2 O, 1/99 (v/v) the emission maximum was red-shifted to 529 nm, indicating a shortening of the effective p-conjugation length due to the introduction of carborane clusters (Table 2). The M n of 38 decreases from 4600 to 3200 with increasing feed ratio.…”

“…The current thiophene derivatives (Chart 6) incorporating the neutral closo or anionic nido carborane cage covalently linked to 3-or 3,4-thiophene moieties or via a phenyl spacer arm are as follows: (i) neutral mono-and di-substituted (27), 15 (28); 15 (30), (31), (32); 18 (34); 19 and (ii) anionic mono-substituted (29) 15 and (33). The polythiophene polymer (PTh) is formed by linking the monomers through their 2,5 positions and become electrically conductive upon partial oxidation.…”

Boron clusters and organic molecules display manifestly different electronic, physical, chemical and geometrical characteristics. These differences highlight the complementarity of organic synthons and boron clusters, and therefore the feasibility of producing hybrid polymers incorporating both types of fragments. This review focuses on the development of hybrid organic-inorganic π conjugated, silane, siloxane and coordination polymers containing icosahedral boron clusters in the last few decades, which have received considerable academic and technological interest due to the combination of the electronic, optical and thermal properties of traditional inorganic materials with many of the desirable properties of organic plastics, including mechanical flexibility and low production costs.

“…[41] Their high fluorescence quantum yield, stimuliresponsive emission, and highly planarized structure make them attractive optoelectronic device materials. [40,42] When a phenylene group is inserted between ethynylenes to yield oligo(phenylene ethynylene)s, the attenuation coefficient increases. Kaliginedi et al [40] and Hong et al [43] investigated the single-molecule conductance of oligo(phenylene ethynylene) s with AuC and AuS σ contacts by the STM-BJ and MCBJ techniques, respectively (Figure 8a,b).…”

Molecular tunnel junctions are organic devices miniaturized to the molecular scale. They serve as a versatile toolbox that can systematically examine charge transport behaviors at the atomic level. The electrical conductance of the molecular wire that bridges the two electrodes in a junction is significantly influenced by its chemical structure, and an intrinsically poor conductance is a major barrier for practical applications toward integrating individual molecules into electronic circuitry. Therefore, highly conjugated molecular wires are attractive as active components for the next‐generation electronic devices, owing to the narrow highest occupied molecular orbital–lowest occupied molecular orbital gaps provided by their extended π‐building blocks. This article aims to highlight the significance of highly conductive molecular wires in molecular electronics, the structures of which are inspired from conductive organic polymers, and presents a body of discussion on molecular wires exhibiting ultralow, zero, or inverted attenuation of tunneling probability at different lengths, along with future directions.

“…[2][3][4] Inorganic-organic hybrid materials have been extensively studied due to their strong chemical bonds like Si-N, B-N and B-O. [5][6][7][8][9][10][11][12][13] The polymers can also be used in the fields of coatings, electron, rocketry, and construction. [14][15][16][17][18] Therefore, these kinds of hybrid materials have good application prospects and research significance.…”

A novel glass fiber reinforced composite was prepared by using silicon‐containing hybrid polymers, poly(methylhydrogen‐diethynylsilyene) (PMES) and poly(phenylethynyl‐silyloxide‐phenylborane) (APABS), as matrix resins. The curing behavior and rheological properties of the matrix resins were investigated by differential scanning calorimetry (DSC) and rotational rheometer. The dynamic viscoelastic properties, mechanical properties, and microstructures of the composites were studied by dynamic mechanical analysis (DMA), universal testing machine (UTM), and scanning electron microscopy (SEM), respectively. The results show that the composite can be well cured between 200 and 300 °C through reactive groups like Si‐H, N‐H, and C≡C units, the possible thermosetting mechanism is also proposed. The composites exhibit excellent mechanical properties with bending strength reach up to 261 and 178 MPa before and after heat‐treating, respectively. SEM analysis clearly indicates that crack in the matrix, matrix/fiber interface debonding, and fiber pull out are predominate failure mechanism for the composites which are heat‐treated in different temperatures. All these obtained results can give theoretical guiding reference for their further applications. Copyright © 2016 John Wiley & Sons, Ltd.
