摘要:
将电子传输型口恶二唑环与空穴传输型咔唑环、蒽环、苯环等芳香环相连,设计合成了4种双光子荧光分子2,5-二[4-(2-芳基乙烯基)苯基]-1,3,4-口恶二唑.通过 Wittig-Horner反应得到标题化合物,用红外光谱、紫外光谱和核磁共振进行了结构表征.所合成的D-π-A-π-D型对称电荷转移化合物具有良好的分子内能量传输性能,因而能够增强双光子荧光发射能力和提高双光子吸收截面.
Abstract:
Four novel 2,5-bis[4-(2-arylvinyl)phenyl]-1,3,4-oxadiazoles that exhibit strong two-photon absorption and enhanced two-photon excited fluorescence were designed and synthesized based on “push-core-pull-core-push” molecules built from embedding electron-transporting 1,3,4-oxadiazole in aromatic conjugated system through Wittig-Horner reaction. Their chemical structures were determined to show trans-vinylene character according to IR and 1H NMR spectra. A very effective energy transfer from the excited units to the π-conjugated bridging unit can enhance the two-photon absorption and two-photon fluorescence.
