Summary: Two simple yet effective strategies (Wittig condensation reaction and radical polymerization) for the synthesis of photochromic copolymers containing bisthienylethene units are presented. A new family of photochromic copolymer containing bisthienylethene and fluorophores units in the main chains was synthesized by Wittig condensation reaction. Another novel photochromic copolymer with multi‐component photochromic pendent groups was prepared by radical polymerization. Photochromism of the copolymers was investigated in solid film and in solution.Photochromic copolymers containing bisthienylethene units.
