Blueish-white-light-emitting Nanographenes Developed by Pd-catalyzed Suzuki-Miyaura Cross Coupling Reactions

Top-down methods produce nanographenes with many carboxy groups on their edges. These functional can be utilized for developing multichromophoric systems. As proof of concept, pyrene is installed the edges by Pd-catalyzed cross-coupling reactions. The lack monomer emissions from functionalized indicates that neighboring chromophores are sufficiently distant to form excimer. pyrene-installed nanographene emits bluish-white-light. Its lipophilic nature allows fabricating a nanographene-dispersed polymethyl methacrylate film emitting visible light. In this communication, we report produced Pd catalyzed Suzuki-Miyaura reaction. formed excimers edge and contribute enhancing photoluminescence nanogrpahenes. allowed fabrication photo thin film.
