Abstract
•Three methylacryloxy 6-nitrospirobenzopyrans were synthesized.•All dyes display photochromic isomerization upon UV irradiation.•Metal complexation generates an intense absorption band with λmax ca. 490 nm.•Polymers synthesized from dyes have similar photochromic properties as in solution.
The synthesis and spectroscopic characterization of several methacryloxy-modified spiropyran dyes is reported. The dyes were found to have similar photochromic isomerization rates relative to a commercially available reference compound in solution. The methacryloxy-modified dyes were also successfully incorporated into polymer matrices, where they retained their ability to photoisomerize and complex with cobalt (II) and zinc (II) ions.
