The structure of 3-(4-bromophenyl)-5-phenyl-4,5-dihydro-1H-pyrazole-1-carbaldehyde was determined by using X-ray diffraction analysis. Photophysical studies of the title compound were investigated in the solvents with different polarities. The emission spectrum of the compound was recorded in polar solvent DMSO (356 nm). In different solvents the extinction coefficients and quantum yield of the compound vary from 1.88 × 104 to 3.53 × 104 and 0.01 to 0.25, respectively. The ratio of the dipole moment of excited state to the dipole moment of ground state was calculated by using solvatochromic shift methods.
