Abstract:This study focuses on six D‐π‐A systems, utilizing diverse π‐spacers as bridges. Comprehensive analysis through Density Functional Theory (DFT) and Time‐dependent Functional Theory (TD‐DFT) methods at B3LYP using 6‐31G (d.p) basis set explores geometrical, electrical, optical, photovoltaic, and absorption properties. EHOMO, ELUMO, and energy gap (Egap), for all of these dyes have been determined and discussed using ground state optimization. TD‐DFT calculates optical properties, unveiling enhanced excitation e… Show more
