- •
Highly congested pyrazole and imidazole ring containing heterocycles were synthesized.
- •
λmax of UV–Vis absorption and photoluminescence (PL) spectra, fluorescence quantum yields of these compounds were studied.
- •
HOMO/LUMO energy levels and the electrochemical band gap (Eg) were investigated.
