Efficient coloration and decoloration reactions of fast photochromic 3H–naphthopyrans in PMMA-b-PBA block copolymer

Fast photochromic molecules have attractive potential to apply to the ophthalmic lenses and real-time dynamic holography.

Summary:Fast photochromic molecules have attractive potential to apply to the ophthalmic lenses and real-time dynamic holography. However, the thermal decoloration reaction rate and the photoconversion efficiency of the photochromic molecules largely depend on their surrounding medium. Herein, we investigated the thermal decoloration behavior of fast photochromic 3H–naphthopyrans in poly(methyl methacrylate)-b-poly(n-butylacrylate) (PMMA-b-PBA) block copolymer. The rapid photoswitching properties of the fast photochromic molecules were achieved by using the block copolymer as a host polymer matrix. [Display omitted] •We developed fast switchable photochromic 3H–naphthopyrans with bulky substituents.•We investigated the thermal decoloration behavior in the PMMA-b-PBA copolymer.•The PMMA-b-PBA copolymer is attractive for fast switchable photochromic molecules.
