Positional isomerism-driven solvatochromism and excited-state behavior in ortho - and para -hydroxy bromobenzylidene Schiff bases: a combined experimental and DFT investigation
Abstract
OH maintains a more rigid and less responsive electronic structure. Thus, this study demonstrates that subtle structural variation through hydroxyl positional isomerism can induce profound changes in electronic structure and excited-state dynamics. These findings provide a clear structure-property relationship and offer a rational strategy for designing Schiff base-based functional materials with tunable optoelectronic properties. This study highlights positional isomerism as an effective molecular design tool for controlling excited-state processes.
