Professor Nugzar Mamardashvili was invited to visit our collegeand give a lecture entitled “Design of Porphyrin-Based Architecture with Well-Defined Geometry and Functional Properties” at the conference hall of The College of Chemistry and Materials Scienceon Oct. 16, 2018. In recent years numerous attempts have been done to design the new porphyrin-based architectures with a well-defined geometry due to their ability to act as molecular receptors for ions recognition and reversible binding of biologically active molecules. In this lecture the synthesis and binding ability of porphyrin-based three-dimensional structures, tetrapyrrolic macrocycles in which are covalently linked with calix[4]arene and calix[4]pyrrole fragments have been discussed. Also, the synthesis and binding properties of porphyrins with two, four and eight 4-carbazolylphenyl-1,2,3-triazole end groups of the first and second generations have been highlighted. It was shown that the conformational changes induced in the architectures upon complexation of the calix[4]pyrrole and calix[4]arene bridging fragments or carbazolylphenyl side branches affect on the binding ability of tetrapyrrolic core toward the substrates of different nature. Selectivity and high sensitivity of the porphyrins to the low-energy effects provide the possibility for controlling the chemical processes occurring with participation of these compounds.

At the end of lecture, the faculty members and students had intensive discussion on the lecture content with Professor Nugzar Mamardashvili. Professor Nugzar Mamardashvilicomprehensively answered the questions with his extensive scientific knowledge and research experience.

Professor Nugzar Zn. Mamardashvili is a Deputy Director on Research of G.A. Krestov Institute of Solution Chemistry of the Russian Academy of Sciences and a head of the laboratory of coordination chemistry of macrocyclic compounds. His current research interests include supramolecular chemistry focusing on porphyrins, the crown-ethers and the calixarenes, their precursors and derivatives, and investigation of molecular recognition of host/guest systems. He is a head of several research grants and author of about 150 publications having h index of 14 (Scopus).
