“…We designed and synthesized unsubstituted 4,4′-bibenzo[c]thiophene 4,4′-BBT and its silyl-substituted derivatives 1,1′-Si-4,4′-BBT and 1,1′,3,3′-Si-4,4′-BBT with one or two tert-butyldimethylsilyl groups on each thiophene ring, as new π-building blocks in emitters, photosensitizers and semiconductors for organic optoelectronic devices. The characterization of 4,4′-BBT, 1,1′-Si-4,4′-BBT and 1,1′,3,3′-Si-4,4′-BBT was successfully determined by FTIR, (1)H and (13)C NMR measurements, high-resolution mass spectrometry (HRMS) analysis, photoabsorption and fluorescence spectroscopy, cyclic voltammetry (CV) and density functional theory (DFT) calculations. …”

“…Thus, it can effectively reduce the reliance on the nonrenewable fossil fuels and avoid the substantial emission of hazardous gases such as CO(2), NO(x), and so on while producing valued-added chemicals. For example, semiconductors can absorb solar light to split H(2)O into H(2) and O(2) or convert CO(2) to alcohols, which can then be used as zero or neutral carbon energy sources. …”

“…According to the molecular design by introduction of hydroxy groups and a ClO(4)(−) anion, many intermediate-strength intermolecular hydrogen bonds (2.6–3.0 Å) were observed in these crystals between electron donor molecules, anions, and included H(2)O solvent, which improve the crystallinity and facilitate the extraction of physical properties. Both salts are semiconductors with relatively low resistivities at room temperature and activation energies of 1.2 ohm cm with E(a) = 86 meV for θ(21)-[(S,S)-2](3)[(R,R)-2](3)(ClO(4))(2) and 0.6 ohm cm with E(a) = 140 meV for α'-[(R,R)-2](2)ClO(4)(H(2)O), respectively. …”
