▎ 摘  要

We have designed and synthesis a new compound of zinc-porphyrin bearing four pyrene groups (ZnP-t-P(py)4) and prepared a new hybrid materials of ZnP-t-P(py)4 with graphene oxide (GO) via non-covalent interactions. The ZnP-t-P(py)4, along with four pendant pyrene entities ZnP-t-P(py)4, stacking on the (GO) surface due to p- p interactions, has been revealed by AFM measurements. FTIR, UV-vis absorption confirm the non-covalent functionalization of the GO. Raman spectral measurements revealed the electronic structure of the GO to be intact upon hybrid formation. In this donor-acceptor nanohybrid, the fluorescence of photoexcited ZnP-t-P(py)4 is effectively quenched by a possible electron-transfer process. The fluorescence and photoelectrical response measurements also showed that this hybrid may act as an efficient photoelectric conversion material for optoelectronic applications.
