Surface-Grafted conjugated polymers for hybrid cellulose materials

摘要

Conjugated polymers were grafted onto cellulose substrates in an effort to create a general method for the synthesis of conjugated polymer/cellulose hybrid materials. In this report, we describe the grafting of poly(fluorene), poly(fluorenevinylene), and a poly(fluorene-ethynylene-phenylene) onto modified cellulose paper substrates using Suzuki, Heck, and Sonogashira-type polymerizations, respectively. The application of these three widely used coupling chemistries to surface-grafted conjugated polymers on cellulose provides a general route to cellulose-based hybrid materials tunable with almost any aromatic repeat structure for specific applications.
