3-Diphenylimidazolyl-substituted 2-hydroxybenzaldehyde has been obtained by the formylation of 2-diphenylimidazolyl-substituted phenol. From the obtained compound, new photochromic spiroindolinebenzopyrans containing a 4,5-diphenylimidazole group at the position 8 of the benzopyran fragment were synthesized. The obtained compounds possess photochromic properties in solution.
