  含羟基和氨基的发色团在双光子吸收诱导下的ESIPT的证据

  摘要：

  本文介绍了在单光子和双光子激发下具有羟基和亚氨基的新型生色团的激发态分子内质子转移（ESIPT）的实验和理论研究。结果表明，内部氢键对2-[（（4'- N，N-二乙基氨基二苯基乙烯-4-ylimino）甲基]苯酚（C1）和2 [[（4'-甲氧基）二苯基乙烯-4-亚氨基]甲基]苯酚（C3）。在单光子和双光子激发下，化合物C1和C3表现出分离良好的双荧光发射带。C1和C3的第二个荧光峰其特点是斯托克斯位移比第一个正常峰值大得多（约140 vs. 30 nm）。4 [[（4'- N，N-二乙基氨基二苯基乙烯-4-ylimino）甲基]苯酚（C2）和4 [[（4'-甲氧基二苯基乙烯-4-ylimino）甲基]苯酚（C4）显示斯托克斯小的单个发射带在一个和两个光子激发下，各种溶剂的位移（约30 nm）。此外，C1和C3的第一发射最大值分别与C2和C4的最大荧光发射波长几乎相同。这些结果表明C1和C3

  In this study, a variety of new conjugated containing strong electron-donating groups were prepared for formation of organic nano-scale aggregates. The properties and aggregation modes of these aggregates were investigated on basis of time dependent absorption, fluorescence emission spectra as well as scanning electron microscope images. The results show that nano organic aggregates could be yielded by the linear dyes in mixed DMF/H2O solvent through a simple re-precipitation method, while no aggregates of the branched dyes were produced. X-ray diffraction of single crystal and X-ray diffraction patterns of the powders results demonstrate that the linear dyes tend to show ordered molecular arrangements, while the armed dyes do not exhibit such a tendency. A remarkable fluorescence switching process under 365 nm lamp was observed for the target aggregates. This study successfully provides real examples of organic aggregates in mixed DMF/H2O solvent which have great capacity to show enhanced fluorescence color switching. (C) 2016 Elsevier Ltd.
