Title: Systematic Investigation of Intramolecular Through-Space Charge Transfer in Naphthalene-Based Systems with Various Donor and Acceptor Moieties
\nAbstract: Charge transfer (CT) is the transition between two states with different charge densities, which involves electron donor-acceptor moieties, and the distribution of charges is the key aspect of such excited states. Our group has recently designed a novel scaffold that facilitates intramolecular through-space charge transfer, incorporating a naphthalene spacer, benzofuran as an electron-donating moiety, and various ynone groups as electron-accepting moieties. This scaffold exhibits a CT band in the visible region in its UV-Vis and fluorescence spectra.<\/p>\n
In this work, we aim to investigate how electronic structures, spatial positioning, and electron density differences influence charge transfer behavior by synthesizing a range of substrates with varying electron-donating and electron-accepting groups. For this purpose, we utilize Sonogashira and Suzuki coupling reactions to synthesize the various target compounds and examine the charge transfer properties. The photophysical properties of the synthesized complexes were analyzed with the help of two main spectroscopic techniques, UV-Vis and fluorescence spectroscopy.<\/p>\n","protected":false},"excerpt":{"rendered":"
