Hirano, Masafumi published the artcileDibenzo[d,d’]benzo[2,1-b:3,4-b’]difurans with extended π-conjugated chains: synthetic approaches and properties, Recommanded Product: 1,3-Dimethoxybenzene, the main research area is bis hexatrienyl dibenzobenzodifuran preparation photopysical photochem DFT.
A series of 3,8-bis(hexatrienyl)-DBBDF compounds I [R1 = H, n-Bu, TMS; R2 = Me, COOMe] and unsym. 8-decyl-3-hexatrienyl-DBBDF compounds II [R3 = H, TMS; R4 = Me, COOMe] were synthesized. Ru-catalyzed cross-dimerization of 3,8-di(hexyn-1-yl)dibenzo[d,d’]benzo[2,1-b,3,4-b’]difuran [3,8-di(hexyn-1-yl)-DBBDF] with 2 equivalent of Me (E)-penta-2,4-dienoate produces a compound I [R1 = n-Bu; R2 = COOMe], and the total yield of obtained from 2,3-difluoro-1,4-diiodobenzene was 50% using the six-step reaction. These compounds were evaluated using UV-visible (UV-vis) spectroscopy and cyclic voltammetry (CV). Time-dependent d.-functional theory (TD-DFT) calculations indicate that efficient π-π* excitations occur using the conjugated trienyl side chain groups.
