Abstract：

Harnessing　the　excited　state　acidity　of　aromatic　alcohols　is　emerging　as　an　effective　approach　for　the　development　of　ring-opening　polymerization　(ROP)　of　lactones　with　additional　control　by　light.　In　view　of　the　wide　presence　of　phenoxy　moieties　in　many　organic　dyes,　we　herein　explore　a　series　of　common　and　commercially　available　organic　dyes　as　potential　photoacid　promotors　for　the　ROP　of　lactones.　Several　organic　dyes,　including　bromocresol　green,　fluorescein,　and　rhodamine　6G,　show　excellent　catalytic　activity　under　the　irradiation　of　visible　light,　affording　polyester　products　with　predictable　molecular　mass　and　narrow　dispersity　(Đ　＜　1.10).　©　2023　The　Royal　Society　of　Chemistry
