Abstract

In this paper we report on the preparation of calix[8]arene functionalized polyglycerol nanogels by miniemulsion polymerization. The gel macromonomers were prepared by anionic ring-opening multibranching polymerization of glycidol using calix[8]arene as initiator. 1,1′,3,3,3′,3′-hexamethyl-2,2′-indotricarbocyanine iodide (HITC) red fluorescent dye was used as a guest molecule. Photobleaching upon strong laser illumination was significantly reduced when the dye was encapsulated inside the nanogel.
