Tetramers based on thiophene and phenylene residues in which the torsion angles between thiophene rings are locked by a chemical bridge have been synthesised by organosynthetic routes. The effect of locking on photoluminescence and absorption in solution has been studied. An enhanced tendency of doubly locked tetrathiophene to aggregate together with its facile decomposition upon light exposure greatly
Novel group 14 element-bridged bithiophene dimers appended with terminal electron-withdrawing groups: Red-to-near infrared fluorescence and efficient photosensitized singlet oxygen generation
significantly efficient 1O2 generation photosensitization upon irradiation of 630 nm light (ΦΔ; 0.88). Considering the result of theoretical calculations showing that the bromo groups effectively contribute to the frontier orbitals, these bromo substituents should facilitate the intersystem crossing from the excited singlet state to the triplet excitedstate through the strong spin‒orbit coupling.
开发了一系列在分子末端带有双氰基乙烯基 (DC) 或硫代巴比妥亚甲基 (TB) 吸电子基团的 14 族元素桥连联噻吩二聚体(E-1a系列和E-1b系列;E = C、Si和Ge)被开发为红色吸收单线态氧 ( 1 O 2 ) 光敏染料。这些染料在红到深红色区域表现出广泛而强烈的吸收和高效的红到 NIR 荧光(光致发光量子产率Φ PL; 0.32–0.45 在二氯甲烷中)。由于更强烈的分子内电荷转移,末端 TB 基团导致比 DC 基团更多的红移电子吸收和荧光发射。采用1,3-二苯基异苯并呋喃法评价E-1a系列和E-1b系列的1 O 2代光敏能力,在630 nm光照射下获得较大的1 O 2代量子产率(Φ Δ),范围为在二氯甲烷中为 0.35 至 0.68。因此,这些染料显示出荧光特性以及1 O 2一代感光能力。在Si-1a和Si-1b的 3,3'-位引入溴基团提供了新的潜在光敏剂Si-2a和S
