Efficient and Tunable White-Light Emission Using a Dispersible Porous Polymer.

A dispersible porous polymer (PEG(113)-b-DVB800-co-AA(200)) 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'eclairage coordinates of (X = 0.33, Y = 0.32).
