Polypyrrole/porphyrin nanohybrid (PPy/Tpp(OH) 4 nanohybrid) have been synthesized through a self-assembled approach, and the as-synthesized PPy/Tpp(OH) 4 nanohybrid are characterized by Fourier-transform infrared, X-ray photoelectron spectroscopy, Raman spectroscopy, thermogravimetric analysis, Ultraviolet-visible absorption, scanning electron microscopy, and steady state fluorescence spectroscopic techniques. Formation of the PPy/Tpp(OH) 4 nanohybrid dramatically improved the solubility and processability of the PPy-based nano-material. The nonlinear optical (NLO) properties of PPy/Tpp(OH) 4 nanohybrid were measured by Z-scan at 532 nm with nanosecond laser pulse, the results indicating that PPy/Tpp(OH) 4 nanohybrid exhibits a enhanced NLO property in comparison with the benchmark PPy and Tpp(OH) 4 due to a combination of mechanisms.
