This research aims to explore how substituents affect the ICT interactions and fluorescence of chalcones.
Analyzed the structure-property relationships of various chalcones
Examined the impact of substituents on fluorescence properties
Investigated the electronic and steric interactions within D–π–A molecules
Fluorescence in chalcones changes with different substituents
Organic compounds show red fluorescence indicating altered ICT interactions
Substituent effects influence the π-conjugation and overall properties
Abstract
In fluorescent chalcones, the ICT interaction in a D–π–A (Donor–π–Acceptor) molecule is perturbed by the electronic and steric interactions of substituents R 1 and R 3 .
