Room temperature phosphorescence of 4-bromo-1,8-naphthalic anhydride derivative-based polyacrylamide copolymer with photo-stimulated responsiveness†
Abstract
Room temperature phosphorescence (RTP) emission was achieved by host–guest recognition between γ-cyclodextrin (γ-CD) and a 4-bromo-1,8-naphthalic anhydride (BrNpA) polymer (poly-BrNpA), which can be controlled by the photo-isomerization of the azobenzene (Azo) unit of the other polymer (poly-Azo) in aqueous solution.
