Three newly designed phenothiazine-based dyes were synthesized in good yield by introducing 1,4,5-tri-Ph imidazole to phenothiazine skeleton linked to benzene, furan or thiophene π-linkers and connected with cyanoacrylic acid acceptor as the anchoring, resp. UV-vis absorption and fluorescence properties of phenothiazine-based dyes were studied in different solvents. Among π-linkers, furan revealed the highest red shift of absorption, followed by thiophene and benzene. The dyes show intense visible absorption with high molar absorptivity; hence good light-harvesting dyes when used as sensitizers. The cyclic voltammetry data revealed that the HOMO energy levels of phenothiazine-based dyes were 5.36 eV for dye I and 5.42 eV for dyes II and III. Also, the energy LUMO levels of phenothiazine-based dyes were -3.10, -3.21, and -3.26 eV for phenothiazine-based dyes, resp. Such well-matched energy levels of these dyes with those reported sensitizers would pave the way for their use in photovoltaic devices. Furthermore, these dyes were investigated by D. Functional Theory (DFT) and time-dependent TD-DFT to explore their potential as efficient dyes in photovoltaic devices. The geometrical structures, optoelectronic properties and charge transfer of these dyes were investigated. The results indicate that the phenothiazine-based dyes have a small energy gap, absorption in the visible and higher oscillator strength. The modification of Ph, furan and thiophene suggests that these dyes could be effective for dye-sensitized solar cells (DSSCs).
