The impact of solvents on the fundamental optical properties of P3DOT
摘要
The influence of solvents on the essential optical characteristics of P3DOT was thoroughly examined. The PhCI solvent yields the highest refractive index (1.90) for the P3DOT at 306 nm, whereas the lowest refractive index (1.54) at 323 nm wavelength is observed with the CH3OH solvent. Single oscillator energy of P3DOT in methanol (CH3OH) as the solvent is measured at 1.35 eV, while the dispersion energy of the material in the same solvent is 0.096 eV. The contrast of P3DOT fluctuates based on the solvent employed, with values varying significantly between 3.85 and 4.0 eV. The P3DOT exhibits its maximum electrical conductivity when dissolved in the PhCI solvent, whereas its minimum electrical conductance is observed in the CH3OH solvent. The findings indicate the electrical conductance of the material can be regulated using different solvents. The electric susceptibility shows a minor increase when dissolved in PhCl, rising from 0.27 to 0.28, corresponding to an energy change from 3.85 to 4.28 eV. In contrast, when dissolved in CH3OH, the electric susceptibility exhibits a more significant increase from 0.19 to 0.22, with energy changing from 3.84 to 4.01 eV. Molar polarizability value of P3DOT, denoted as (αj) was determined to be
