▎ 摘　　要

An organic-inorganic nanohybrid material (TPPOH-GO) is produced by linking monohydroxyporphyrin (TPPOH) and graphene oxide (GO) together via the ester bond, and the formation of this nanohybrid has been affirmed by various spectroscopy techniques. Nonlinear optical (NW) and optical limiting (OL) performances were studied by the Z-scan technique. Because of the efficient electric charge transfer efficiency between TPPOH and GO, the as-prepared TPPOH-GO nanohybrid exhibits superior NLO and OL performances compared to those of TPPOH and GO. The photophysical, NLO and OL performances of hydrothermally reduced materials (TPPOH-RGO 1, TPPOH-RGO 2, TPPOH-RGO 3) are tuned by controlling the hydrothermal temperatures, implying the scope of using them as optical limiters.
