为了在农业领域促进光合作用，本文报道了利用主客体效应和光聚合反应对有机荧光染料的溶液处理分子取向控制。研究了染料/聚合物共混膜中分子构象与偏振光致发光特性的关系。实验结果表明，染料分子的浓度猝灭效应减弱，并出现了无序区。讨论了利用液晶单体和荧光染料制备高度有序固态薄膜的溶液工艺和材料。
For photosynthesis promotion in the field of agriculture, we report on solution-processed molecular alignment control of organic fluorescent dye using guest-host effect and photo-polymerization reaction in this paper. We investigated the relation between molecular conformation and polarized photoluminescence characteristics in dye/polymer blend films. As the result, we observed polarized photoluminescence with reduction of concentration quenching effect and disordered region of dye molecules. We discussed the solution process and materials for highly-ordered solid-state films using liquid crystalline monomer and fluorescent dye.
