Title :

Functional Supramolecular Polymers of Extended π-Systems

Abstract :

Supramolecular polymers derived from novel π-conjugated molecules are promising candidates for modern electronic and photonic devices owing to their high internal order and strong exciton coupling1. Moreover, they are easy to process, dynamic, reversible and recyclable which are not observed in many of the covalent polymers. However, most of the supramolecular polymers are reported to have low mobility of charge carriers and often depolymerize into monomers at high temperatures2. In my talk, I will discuss about some of our strategies to improve the charge carrier mobility and thermal stability of supramolecular polymers of various extended π-systems3–5.
