Benzotriazole-based donor-acceptor type low band gap polymers with a siloxane-terminated side-chain for electrochromic applications

A series of donor–acceptor (D-A) type polymers (P1-P4) bearing a benzotriazole group with a siloxane terminated side-chain and a long alkyl chain were synthesized via Stille coupling, and the electrochromic (EC) properties were characterized by various analytical techniques. The incorporation of hybrid siloxane-solubilizing groups in P1 and P2 influenced the intermolecular interactions among the adjacent polymer chains and increased the solubility of the resulting polymers in common organic solvents. The EC behavior of the polymers revealed a color transition from red to blue upon oxidation and reduction. In particular, P1, containing a short siloxane-terminated side-chain, showed superior optical performances, with transmittance change of 42.7%, the change in optical density of 0.767, and coloration efficiency of up to 327?cm2/C, and exhibited superior operational stability, with little transmittance changes after 100 potential steps. Overall, these properties highlight the potential applications of current polymers in displays and smart windows.

Strongly luminescent and liquid-crystalline π-conjugated 2-methyl[1,2,3]benzotriazoles with a linear donor-acceptor-donor structure

Symmetrical 2-methyl[1,2,3]benzotriazole (BZT) derivatives with elongated peripheral units connected via acetylenic triple bonds present calamitic thermotropic mesomorphism with nematic and smectic phases. They show intense photoluminescence with near-unity quantum yields in solution. The peripheral groups significantly influence the excited-state lifetime. Fluorescence quenching is observed in the presence of C60, testifying of charge transfer to the fullerene acceptor. The varying sterical demand of the different substituents considerably influences the efficiency of the charge transfer induced fluorescence quenching. HOMO, LUMO and band gap energies ranged from ?5.15 to ?5.97 eV (ionization potential), ?2.47 to ?2.96 eV (electron affinity) and 2.68 to 3.08 eV (optical band gap).

Benzimidazole-Branched Isomeric Dyes: Effect of Molecular Constitution on Photophysical, Electrochemical, and Photovoltaic Properties

Three benzimidazole-based isomeric organic dyes possessing two triphenylamine donors and a cyanoacrylic acid acceptor are prepared by stoichiometrically controlled Stille or Suzuki-Miyaura coupling reaction which predominantly occurs on the N-butyl side of benzimidazole due to electronic preferences. Combined with the steric effect of the N-butyl substituent, placement of the acceptor segment at various nuclear positions of benzimidazole such as C2, C4, and C7 led to remarkable variations in intramolecular charge transfer absorption, electron injection efficiency, and charge recombination kinetics. The substitution of acceptor on the C4 led to red-shifted absorption, while that on C7 retarded the charge transfer due to twisting in the structure caused by the butyl group. Because of the cross-conjugation nature and poor electronic interaction between the donor and acceptor, the dye containing triphenylamine units on C4 and C7 and the acceptor unit on C2 showed the low oxidation potential. Thus, this dye possesses favorable HOMO and LUMO energy levels to render efficient sensitizing action in solar cells. Consequently, it results in high power conversion efficiency (5.01%) in the series with high photocurrent density and open circuit voltage. The high photocurrent generation by this dye is reasoned to it exceptional charge collection efficiency as determined from the electron impedance spectroscopy.
