Photochromic cross-linked copolymer containing thermally stable fluorescing 2-indolylfulgimide
Abstract
A new photochromic cross-linked copolymer composed of PMMA and fluorescing 2-indolylfulgimide is synthesized which can be converted photochemically into two forms which are found to be thermally stable; the spectroscopic properties and quantum yields of photochemistry and fluorescence are also measured.
