A series of chromophores was designed and synthesized using 2-(3-cyano-4,5,5-trimethylfuran-2 (5H) -ylidene) malononitrile (TCF) as the electron acceptor and differing from each other by the use of thirteen different electron donors. The different dyes were characterized for their optical and electrochemical properties and theoretical calculations were also carried out to support the experimental results. By changing the electron donor in the thirteen dyes, chromophores absorbing between 430 nm and 700 nm could be synthesized. Solvatochromism of the different dyes was analyzed in 23 solvents of different polarity and a positive solvatochromism was determined for all chromophores using the semi-empirical solvent polarity scales based on the Kamlet-Taft parameters (π *) or the Catalan parameters (SdP and SPP).

基于2-(3-氰基-4,5,5-三甲基呋喃-2(5 H)-亚烷基)丙二腈(TCF)受体的一系列推挽染料的合成,光学和电化学性质

以2-(3-氰基-4,5,5-三甲基呋喃-2(5 H)-亚烷基)丙二腈(TCF)为电子受体,设计并合成了一系列生色团,其中十三种彼此不同不同的电子给体 对不同染料的光学和电化学性质进行了表征,并进行了理论计算以支持实验结果。通过改变十三种染料中的电子给体,可以合成吸收在430 nm和700 nm之间的发色团。在23种不同极性的溶剂中分析了不同染料的溶剂变色现象,并基于Kamlet-Taft参数(π*)或加泰罗尼亚参数(SdP和SPP),使用半经验溶剂极性标度对所有生色团确定了正溶剂化变色现象。
