  Synthesis and fluorescence of dicyanoisophorone derivatives

  摘要：

  A class of dicyanoisophorone derivatives 1-5 with electron-donating groups has been prepared by a two-step condensation reaction. Fluorescence both in solution and in pure solid state are measured. It is found that dicyanoisophorone derivatives 1-5 exhibit fluorescence in both solution and pure solid state. An enhancement of fluorescence in solid state probably results from the aggregation-induced emission. It is also found that dicyanoisophorone derivatives 1-5 show large Stoke's shifts in solution as well as in pure solid state. The origin of fluorescence of dicyanoisophorone derivatives depends on the nature of substituents, with a strong push pull chromophores dicyanoisophorone system, red or orange solid-state fluorescence is obtained.

  A series of fluorescent molecular rotors obtained by introducing two rotational groups (“rotators”), which exhibit different rotational and electron‐donating abilities, are discussed. Whereas the control molecular rotor, PH, includes a single rotator (the widely used phenyl group), the PO molecular rotors consist of two rotators (a phenyl group and an alkoxy group), which exhibit simultaneous strongly

  讨论了通过引入两个旋转基团（“转子”）获得的一系列荧光分子转子，这些旋转基团表现出不同的旋转能力和给电子能力。控制分子转子PH包括单个转子（广泛使用的苯基），而PO分子转子则由两个转子（苯基和烷氧基）组成，它们同时具有很强的供电子性和易旋转性。与控制转子PH相比，PO分子转子表现出高出一个数量级的量子产率（荧光强度），同时表现出明显更高的荧光对比度。这些性质与烷氧基的强大的供电子能力和低的旋转能量垒直接相关，如动态荧光实验和量子化学计算所证实。PO分子转子表现出两个荧光弛豫路径，而PH分子转子表现出单个荧光弛豫路径。成功地证明了使用PO分子转子对细胞粘度作图的细胞荧光成像。
