ABSTRACT
Recently, photophysical property with fluorescence function has been attracted and studied because there are promising potentials in academic and industrial applications. Organic materials having fluorescence effect, especially fluorochromism can be utilized in the sensing or probing with absorption/emission changes. Herein, the prepared dye chromophore can be changed to their optical properties with polar/non-polar environmental media. In this work, we synthesized a new fluorochromism dye, namely 5-[2-(4-diphenylamino-phenyl)-vinyl]-2,2-dimethyl-[1,3]dioxane-4,6-dione using 3-formyl triphenylamine and 2,2-dimethyl-[1,3]dioxane-4,6-dione. We investigated absorption and fluorescent emission in various solvent media. Furthermore, cyclovoltammogram was used to determine energy levels of HOMO/LUMO from their redox onset potentials. Measured energy levels of HOMO/LUMO were compared with the results of simulated computational calculation.
