Spectroscopic nonlinear optical characteristics of porphyrin-functionalized nanocomposite materials

Due to its attractive characteristics, Porphyrin is an excellent option for the identification of numerous analytes. Porphyrins have demonstrated high potential in photocatalytic applications in visible light, due to their electrical, optical, and catalytic properties. Research on porphyrin nanomaterials has been published recently as they offer a reliable sensing platform to identify diverse analytes in environment, health, and food. Spectroscopy techniques have been employed extensively in the chemical, biological, and engineering domains. Numerous spectroscopic approaches are now used to characterize Porphyrin Functionalized materials composites as it has grown into a separate field and nonlinear optical (NLO) studies Intense light fields' interactions with materials in the aspects of the structure of matter, reaction processes on the entire instance scales, as well as the formation of novel states, phases, or even novel matter for research purpose in the field of science, technology, and medicine. This chapter investigates the structure, spectroscopic properties, and nonlinear optical behavior of porphyrin-based nano-composites achieved through covalent functionalization.
