The photochemical preparation of benzo[4,5]imidazo[2,1-b]quinazoline was assessed under the illumination of UV wavelength (>360 nm). The compound 3,4-dihydronaphthalen-1(2H)-one 1 with 1H-benzo[d]imidazol-2-amine 2 in the existence of KOH/DMF which lead to the aromatized compound 3. The notable remark of this reaction is that the UV irradiation (312 nm) plays a vital part in the formation of compound, 3 in shorter duration (2 h) which resulted in higher yield of 96%. Compound 3 was analyzed by H1, C13 NMR, and HRMS. Solvatochromism impacts of the compound 3 was computed with different solvents (DCM
