Theoretical Study on Vibrationally Resolved Electronic Spectra of Chiral Nanographenes

Molecules, Год журнала: 2024, Номер 29(17), С. 3999 - 3999

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,

Tether-entangled conjugated helices

Chemical Science, Год журнала: 2024, Номер unknown

Опубликована: Янв. 1, 2024

A tether-entangled conjugated helices (TECHs) concept is introduced for helical polyaromatic molecules. TECHs can be directly constructed in enantiopure form with excellent configurational stability and persistent chiroptical properties.
