Abstract: The last two decades have witnessed a phenomenal growth of research in nonlinear optical (NLO) properties of various conjugated polymers, molecular solids, organic and organometallic compounds. Porphyrins, metalloporphyrins and their derivatives are one of the most studied groups of organic molecules due to their favourable electronic, chemical, thermal and structural properties which make them useful for a variety of NLO applications. Zn(II) metalloporphyrin coordination complexes and covalent systems with various architectures have been assembled. Their NLO properties were investigated using Z-scan and degenerate four-wave mixing (DFWM) techniques. This work provides an insight on the influence of monomer conformation on architecture which in turns determines NLO properties. The effects of conformation and configuration of a series of water-soluble porphyrins on molecular recognition is also demonstrated. In our endeavour to discover new compounds with for NLO applications, a first ever study of benzo[c]cinnoline conjugated polymeric systems was conducted in this work.
