  New organic conjugated dye nano-aggregates exhibiting naked-eye fluorescence color switching

  摘要：

  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.

  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

  A series of new one, two, and three-branched two-photon absorption triazine derivatives with a π-bond and a σ-electron pair as a bridge have been synthesized and their photophysical properties have been systematically investigated. These chromophores showed obvious solvatochromic effects, i.e., significant bathochromic shifting of the emission spectra and larger Stokes shifts were observed in more

  合成了一系列新的一，二和三支双光子吸收三嗪衍生物，它们以π键和σ电子对为桥，并且系统地研究了它们的光物理性质。这些生色团显示出明显的溶剂变色作用，即，发射光谱的显着红移和在极性更大的溶剂中观察到更大的斯托克斯位移，这主要是由于分子内电荷转移（ICT）所致。通过在DMF中的双光子激发荧光（TPEF）测量来确定双光子吸收（2PA）横截面值。该结果进一步证明，作为π桥的σ电子对是转移电荷的有效方式，并且其2PA截面值（δ）随着分支数的增加而增加。
