Five boron-centered spiro compounds with imidazo[1,5-]pyridin-3-yl phenols as ligands were synthesized and thoroughly characterized through H-NMR, C-NMR, infrared spectroscopy, and X-ray single crystal analysis. The fluorescence properties of these compounds in solution and in the solid state were investigated, revealing blue emission with wavelengths maxima dependent on the electronic properties of the substituents on the ligands in solution, and an orange-red emission in the solid state. Time-Dependent Density Functional Theory (TD-DFT) calculations were performed to describe the nature of the transitions.
合成了五种以咪唑并[1,5 -]吡啶 - 3 - 基苯酚为配体的硼中心螺环化合物，并通过氢核磁共振（H-NMR）、碳核磁共振（C-NMR）、红外光谱和X射线单晶分析对其进行了全面表征。研究了这些化合物在溶液和固态中的荧光性质，结果表明在溶液中其发射蓝光，最大波长取决于配体上取代基的电子性质，而在固态中则发射橙红色光。进行了含时密度泛函理论（TD-DFT）计算以描述跃迁的性质。
