Theoretical Study on Vibrationally Resolved Electronic Spectra of Chiral Nanographenes

Molecules, Journal Year: 2024, Volume and Issue: 29(17), P. 3999 - 3999

Published: Aug. 23, 2024

Nanographenes are of increasing importance owing to their potential applications in the photoelectronic field. Meanwhile, recent studies have primarily focused on pure electronic spectra nanographenes, which been found be inadequate for describing experimental that contain vibronic progressions. In this study, we effect transition a range chiral especially low-energy regions with distinct progressions, using theoretical calculations. All calculations were performed at PBE0-D3(BJ)/def2-TZVP level theory, adopting both time-dependent and time-independent approaches Franck-Condon approximation. The resulting calculated curves exhibited good alignment data. Notably, nanographenes incorporating helicene units,
