摘要/Abstract
以5-甲氧基-2-氨基苯甲酰胺与2-甲基吡啶为原料，通过简单的两步反应合成了6-甲氧基喹唑啉酮-吡啶二氟硼化合物（BODIQPy）.这种甲氧基取代的BODIQPy具有良好的溶液荧光和固态发光性质.通过甲氧基的引入，增强了BODIQPy的电荷转移特性，得到了超大斯托克斯位移.同时还讨论了5-位吡啶取代的卤素对BODIQPy发光性质的影响.

6-Methoxyquinazolinone-pyridine difluoroboron dyes (BODIQPys) have been synthesized in two simple steps with 2-amino-5-methoxybenzamide and 2-methylpyridines as starting materials. These quinazolinone-based difluoroboron (BF2) complexes exhibited highly efficient green luminescence and remarkable fluorescence in the solid-state with very large Stokes shift (Δλ up to 220 nm in MeCN). The introduction of methoxy group at 6-position of BODIQPy caused the red-shifted emission by the enhancement of charge transfer property. The introduction of halogen atom at pyridine moiety of BODIQPy can tune the LUMO levels in regularity while their HOMO levels remain intact.
Key words: quinazolinone, difluoroboron complexes, fluorescent dyes, solid state luminescence
