Novel bichromophores YL3 based on julolidine donor chromophores were synthesized via a Cu(I) catalyzed click-reaction and systematically characterized in this paper. YL3 showed good thermal stability, solubility and transparency properties. Besides, the high molecular hyperpolarizability of bichromophores YL3 can be effectively translated into large electro-optic coefficients. In electro-optic activities, the doped film YL3-amorphous polycarbonate (APC) showed an electro-optic coefficient (r₃₃) of 183 pm V⁻¹. This value is much more than the electro-optic (EO) activity of the monochromophore (114 pm V⁻¹) with similar structure. This result meant that the new structure of bichromophores YL3 can reduce intermolecular electrostatic interactions, thus enhancing macroscopic EO activity. These properties suggested the potential use of the new bichromophores in nonlinear optical materials.

一种新型的基于菊糖苷发色团的双色团，具有从超极化性β到电光活性的增强的转移效率

本文通过Cu（I）催化的点击反应合成了基于聚j啶供体发色团的新型双发色团YL3，并对其进行了系统地表征。YL3具有良好的热稳定性，溶解性和透明性。此外，双色团YL3的高分子超极化能力可以有效地转化为大的电光系数。在电光活动中，掺杂膜YL3无定形聚碳酸酯（APC）的电光系数（r ₃₃）为183 pm V ^-1。该值远大于单色团的电光（EO）活性（114 pm V ^-1），结构相似。该结果意味着双色团YL3的新结构可以减少分子间静电相互作用，从而增强宏观的EO活性。这些性质表明，新的双色团在非线性光学材料中的潜在用途。
