8-苯基-BODIPY 505/515是一种以苯基取代的BODIPY衍生物,作为一种荧光团,它可以作为荧光探针使用。
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.
