选择对氧有敏感响应的4,7-二苯基-1,10-邻菲咯啉钌[Ru(dpp)]为荧光猝灭探针,通过条件优化,制备了粒径100nm左右且包埋有该荧光探针的聚丙烯腈纳米颗粒。研究结果表明,包埋于聚丙烯腈材料中的Ru(dpp)较好保持了原有的荧光特性和稳定性。丙烯腈纳米颗粒在100%氮氧改变的环境中,其荧光强度变化小于2%,显示了较好的隔氧效果。 4,7-diphenyl-1,10-phenanthroline ruthenium [Ru (dpp)], which is sensitive to oxygen, was chosen as the fluorescence quenching probe. By optimizing the conditions, Polyacrylonitrile nanoparticles with this fluorescent probe. The results show that the Ru (dpp) embedded in polyacrylonitrile material retains the original fluorescence characteristics and stability. Acrylonitrile nanoparticles in 100% nitrogen and oxygen changes in the environment, its fluorescence intensity changes less than 2%, showing a better oxygen barrier effect.
