Abstract

Indoline spirochromenes (spiropyrans) with various alkyl (C2–C10) groups attached to the nitrogen atom were synthesized. The majority of them are photochromic in the crystalline state. The packing density of the spirochromene molecules in crystals decreases as the length of the alkyl groups attached to the nitrogen atom increases, and this explains the decrease in the melting points and the appearance of photochromic properties in the crystalline state.
