通过元素分析、紫外-可见吸收光谱和核磁共振氢谱，证实了一种易于超极化的3-苯氧丙烷- 1,2 -二醇双色团的结构。将双色团和相应的单色团掺杂到聚4-乙烯基苯酚中制备了非线性光学聚合物薄膜。原位二次谐波产生测量结果表明，双色团的二次谐波产生系数提高了2.2倍，表明新型3-苯氧丙烷- 1,2 -二醇衍生物可用于设计和合成具有大宏观光学非线性的多色树状大分子。
The structure of a novel bichromophore that comprised a readily hyperpolarisable chromophore with 3-phenoxypropane-1, 2-diol via esterification, was confirmed by elemental analysis, UV–visible absorption spectra and1H NMR. Nonlinear optical polymer films were fabricated by doping the bichromophore and the corresponding monochromophore into poly(4-vinylphenol). In situ second harmonic generation measurements revealed that the bichromophore imparted a 2.2-fold enhancement in the second harmonic generation coefficients of the films, indicating that the novel 3-phenoxypropane-1, 2-diol derivative could be used in the design and synthesis of multi-chromophoric dendrimers with large macroscopic optical nonlinearity.
