The use of atom transfer radical polymerization (ARTP), a living radical polymerization method, for controlling the photochromism through local environment effects was described. ARTP allowed the creation of polystyrene-spirooxazine conjugates consisting of polystyrene of known molecular weight with a single spirooxazine dye attached at the end. The control of photochromic coloration and fade speeds was found to be dependent on the choice of the size of the polymer conjugate with no modification to the electronic structure of the dye required. The results show that the molecular weight has an effect on the chain rigidity and thus, has an effect on the local environment of the photochromic molecules.
