| 摘 要： | 合成了二种新的分子内电荷转移化合物:双(p-N,N-二甲氨基苯乙烯基)偏二氰乙烯(Ⅱ)及(p-N,N-二甲氨基苯乙烯基)苯基偏二氰乙烯(Ⅱ)。并对它们在不同极性溶剂中的光谱和光物理行为进行了研究。结果表明:化合物(Ⅰ)的荧光量子产率随溶剂极性增大而不断提高,而化合物(Ⅱ)的荧光量子产率则随溶剂极性增大出现了一极大值。对这一现象的产生进行了初步讨论。

| Abstract: | In this work, two new intramolecular charge transfer compounds Bis(p-N,N-dimethyl-aminostyryl)malononitrile (Ⅰ) and (p-N, N-dimethylaminostyryl)phenylmalononitrile(Ⅱ)] were synthesized and characterized. The spectra and photophysical behavior were studied in diffe-cent solvents. Results showed that the fluorescence quantum yield for compound (Ⅰ) increased, but that for compound (Ⅱ) had a maximum with the increasing of the solvent polarity. This phenomenon was discussed preliminarily. |
