Substituents Effects on Properties of PeryleneDyes for Spectrum Conversion Film. |
| 초록 |
Wesynthesized dyes suitable for spectrum conversion film (SCF) based on perylene dye. Photophysicalproperties, optimized structures, and energy states were investigated. Also, thermal stability of the dyes was investigated. Stokesshift and fluorescence quantum yields of the dyes in solution state increasedas the volume of the bay position-substituents increased. We compared theStokes shift of each dye by comparing the structural difference between S0and S1 states of each compound. Also, we investigated the quenchingconstant and molar volume of the dyes to verify the relationbetween the degree of intermolecular steric hindrance and the degree ofaggregation caused quenching (ACQ). Lastly, PMMA films doped with the dyes werefabricated, and photophysical properties were investigated. Thephotosynthesis rate and growth of the lettuce were measured by the film dopedwith PI-TBPO, which shows the best properties among the dyes. |
