▎ 摘　　要

Electrically conducting matrix comprised of graphene and organic molecule is immensely versatile and has a broad range of potential applications. Highly soluble zinc tetra-tert-butyl phthalocyanine-reduced graphene oxide (ZnTTBPc-RGO) blend samples have been synthesized with different RGO concentrations (0-1 volume fraction). The electrical conductivity of ZnTTBPc-RGO samples indicates a percolating behavior with the three-dimensional percolation threshold of similar to 0.167 vol. fraction of RGO. Room temperature as well as temperature dependent (100-320 K) photosensitivity (P) measurements go through a maximum at similar to 0.33 vol. fraction of RGO content (namely sample G). Calculated P values exhibit a decreasing trend with increasing temperature and have been ascribed to enhanced scattering mechanisms. Resistivity data suggest that the charge transport process of ZnTTBPc-RGO is consistent with Efros-Shklovskii variable range hopping mechanism at 88-320 K. Moreover, comprehensive measurements on nonlinear absorption (NLA) of ZnTTBPc-RGO show a significant enhancement in nonlinear optical properties compared to pure ZnTTBPc when measured with similar to 100 fs, 1 kHz laser pulse at 540 nm in an intensity range of 37-130 GW/cm(2). Comparative measurements on P and NLA coefficient show highest values for sample G compared to others along with faster electron transfer rate, confirmed by femtosecond transient absorption spectroscopy measurements. These results provide a way of characterizing ZnTTBPc-RGO blend for optoelectronic device applications.
