Abstract

Abstract: We present a general procedure for the synthesis and in situ functionalization of highly fluorescent non-conjugated polymer dots, by exploiting the room-temperature carbodiimide-mediated condensation between citric acid and amines. The versatility of this method is proved by the preparation and characterization of a broad set of fluorescent nanoparticles with customized polymer structures and functional groups. Graphical abstract: Image 1 Highlights: The rational design of highly fluorescent non-conjugated polymer dots was achieved. Pathways for in situ functionalization were successfully demonstrated. Polymer dots with defined chemical structure and functionalities were obtained.
