Formation and Photoinduced Electron Transfer in Porphyrin- and Phthalocyanine-Bearing N-Doped Graphene Hybrids Synthesized by Click Chemistry

Description: Article presents research where N-doped graphene (NG) has been covalently decorated with porphyrin and phthalocyanine moieties using click chemistry. Evidence of charge separation in these hybrids is secured from femtosecond transient absorption studies, acting NG as electron acceptor.
