[Paper] Polarized Photoluminescence Characteristics of Uniaxially-Aligned Fluorescent Dye with Liquid Crystalline Polymer for Agricultural Applications

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.
