Abstract

Two novel photochromic macrocycles 1 and 2 bearing dithienylethene units and urea building blocks have been synthesized, and their photochromic properties are described. Macrocycle 2 shows good photochromic properties, while the relatively smaller size of macrocycle 8b exhibits photochemically inactive properties due to the unfavourable ring conformational constraint. Moreover, the crystal structures of the urea-protected precursor macrocyles 3a, 3b, and 8b are presented.
