fluorescence sensing multicomponent molecular device based on 1,8-naphthalimide fluorophores is synthesized and investigated. The system is designed as a light-harvesting antenna where energy supplier, molecular rotor and molecular “on-off” switcher are integrated. The peripheral 1,8-naphthalimide energy suppliers transfer rapidly the trapped energy to the core molecular rotor through high efficient FRET (99
合成并研究了一种新型的基于1,8-萘二甲酰亚胺荧光团的pH和粘度荧光传感多组分分子器件。该系统被设计为集能量供应器,分子转子和分子“开关”切换器的光收集天线。外围的1,8-萘二甲酰亚胺能量供应商通过高效的FRET(99%)将捕获的能量迅速转移到核心分子转子。4-哌嗪基-1,8-萘二甲酰亚胺核的激发导致TICT驱动的分子运动。由于TICT核心荧光团的非发射消磁特性,系统显示出低黄绿色荧光,即“通电” /“转子通电”状态。甲基哌嗪胺的质子化使TICT工艺不稳定,因此表明系统处于“通电” /“转子关闭”状态。
