摘　　要：合成了一种BODIPY三联吡啶化合物(BODIPY-DT),所得化合物对溶剂DMF具有选择性变色响应。研究表明,变色机理是因为BODIPY自身是一种良好的光敏剂,在DMF溶液中能更好地诱导产生单线态氧,其能将分子中的炔键和BODIPY荧光团骨架氧化,进而产生溶液颜色和荧光的变化。将此科研成果引入到实验教学中,设计开展综合性实验教学,有利于促进教学与科研的相互融合。A novel BODIPY(boradiazaindacene)dye denoted as BODIPY-DT containing terpyridine unit has been designed and characterized.The dye is found to be selective and visual solvatochromic sensor toward DMF among test organic solvents.The mechanism of discoloration was discussed theoretically.It is because BODIPY-DT can generate singlet oxygen efficiently in specific solvent of DMF in sunlight at room temperature.The compound in DMF can further be oxidized by singlet oxygen via radical reaction and the oxidization process displays dynamic emission colors.We designed and carried out comprehensive experimental teaching by introducing the research achievement.
