通过 Knoevenagel 缩合反应很容易合成 3,/3,5-二噻吩并硅咯-乙烯基-BODIPY。研究了两种染料在不同溶剂中的光谱性质。染料 1 和 2 在 DCM 中在 620 和 738 nm 处显示最大吸收,吸收系数分别为 60900 和 77900 [公式:见正文] cm[公式:见正文]。相对于母体 1,3,5,7-四甲基-BODIPY,观察到主光谱带显着红移。 TD-DFT 计算再现了光谱位移和实验光谱。
3,/3,5-Dithienosilole-vinyl-BODIPYs were readily synthesized through Knoevenagel condensation reactions. Spectroscopic properties of two dyes in various solvents were investigated. Dyes 1 and 2 show an absorption maxima at 620 and 738 nm with absorption coefficient of 60900 and 77900 [Formula: see text] cm[Formula: see text] in DCM, respectively. Significant red shifts of the main spectral bands are observed relative to that of the parent 1,3,5,7-tetramethyl-BODIPY. TD-DFT calculations reproduce the spectral shifts and experimental spectra.
