Executive Summary : | Objective: To develop a p-extension reaction via "bottom-up annulations" of arynes for synthesis of p–extended carbon materials. The photophysical properties of the synthesized material would be envisaged and would be utilized to realize efficient fluorescent probes for photonic applications. Summary: p–Extended carbon materials are ubiquitous compounds in nature. The synthesis of controlled large polycyclic aromatic systems and/or its derivatives is an important challenge in chemistry. They serves as an active components for electronic and optoelectronic devices, such as light-emitting diodes, field-effect transistors (FETs), and solar cells. The properties of p–extended carbon materials depend on its size, shape, and peripheral functionalization of the polycyclic system. These significant characteristics of p–extended carbon materials has renewed the interest of organic chemist in the synthesis of large poly aromatic compounds (PACs) such as fullerenes, carbon nanotubes (CNTs), graphene and other carbon nanostructure. The generally adopted strategies for the synthesis include thermolysis, oxidative photocyclizations, Diels-Alder reactions and various metal-catalyzed cross-coupling and cycloaddition reactions. Recently, highly reactive and rich chemistry of arynes have been extensively exploited for the construction of extended and/or complex polycyclic aromatic compounds. In this proposal we are planning to develop a p-extension reaction via "bottom-up annulations" of arynes for synthesis of p–extended carbon materials. The photophysical properties of the synthesized material would be envisaged and would be utilized to realize efficient fluorescent probes for photonic applications. |
