Three types of novel photochromic indolinobenzospiropyran-based homopolymers were prepared via the ring-openingmetathesispolymerization of the strained bicyclic indolinobenzospiropyran derivative. The homopolymers were soluble in common organic solvents and displayed unusually high polydispersity as determined by gel permeation chromatographic analysis.
