The title compound, C 21 H 17 FN 2 , was prepared from phenylhydrazine and 1-phenyl-3-(p-fluorophenyl)-2-propenyl-1ketone. The pyrazolinyl ring forms dihedral angles of 11.87 (12), 8.30 (12) and 65.89 (12) with phenyl rings at the 1 and 3 positions and the fluorophenyl ring, respectively.
Diphenyl-3-naphthyl-2-pyrazoline nanocrystals with different sizes from 400 to 20 nm were prepared by the reprecipitation method. As the nanocrystal size decreased, the nanocrystal absorption peak was observed to shift to high-energy side due to size effect, and in the same period the peak shape cha
