Efficient and tunable white‐light emission using a dispersible porous polymer

Abstract

A dispersible porous polymer (PEG113‐b ‐DVB800‐co ‐AA200) based on the controlled radical polymerization of divinylbenzene and acrylic acid with a poly(ethylene glycol) (PEG) macrochain transfer agent (macro‐CTA) is synthesized and postsynthetically modified with anthracene. This blue‐emitting porous polymer is used to encapsulate the yellow‐emitting fluorophore rhodamine B into its core, resulting in a white‐light emitting dispersion with a quantum yield of 38% and commission internationale de l’éclairage coordinates of (X = 0.33, Y = 0.32).
