meso-Cyano boron-pyridyl-isoindoline dyes with asymmetrical structures were synthesized through a facile two-step reaction. Broad envelopes of intense vibrational bands were observed for the main spectral bands in the absorption and emission spectra. Moderate fluorescence quantum yields were obtained in solution, with significant intensity also observed in film, powder and crystal forms. An analysis of the structure-property relationships was carried out based on X-ray crystallography, optical spectroscopy, and theoretical calculations.
通过简便的两步反应合成了具有不对称结构的中位氰基硼-吡啶基异吲哚啉染料。在吸收光谱和发射光谱中，主光谱带观察到宽的强振动带包络。在溶液中获得了适度的荧光量子产率，在薄膜、粉末和晶体形式中也观察到显著的强度。基于X射线晶体学、光谱学和理论计算对结构-性质关系进行了分析。
