【摘要】 以噻吩嗪和2-苯基-6-溴-呋喃[2, 3-b]喹喔啉为原料制备了多功能有机发光分子—6-PTZ-FQ。6-PTZ-FQ具有热活化延迟荧光发射、力致变色发光、聚集诱导发光及室温磷光性能。利用荧光光谱仪研究了材料的光物理特征,设计实验观察了各个特征发光现象,阐述了各个发光现象产生的机理和相互切换的依赖关系。实验具有创新性、综合性和可操作性,有助于培养学生的实践能力、辩证思维、综合解决问题的能力和创新能力。更多还原

【Abstract】 A multifunctional emitter, 6-PTZ-FQ, was synthesized using phenothiazine and 2-Phenyl-6-bromofuro [2, 3-b] quinoxaline as stating materials. The compound simultaneously owns thermally activated delayed fluorescence, mechanochromic luminescence, aggregation induced emission and room temperature phosphorescent. Their photophysical properties were investigated by FLS 980fluorescent spectrometer. The designed experiments demonstrated the luminous characteristics above,and underlying mechanisms were explained. This innovation experiment is comprehensive and feasible.We hope the designed experiment could help student to improve their practical ability, dialectical thinking ability, problem-solving ability and innovative ability.更多还原
