Efficient Molecular Array Control and Vapochromic Behavior Changes by Positional Isomer‐Dependent Molecular Building Blocks (Advanced Optical Materials 28/2024)

Efficient Molecular Array Control and Vapochromic Behavior Changes The study by Kyung-Ryang Wee and co-workers in article number 2401305 introduces a strategy to control molecular arrays by modifying the shapes of donor–acceptor–donor building blocks via positional isomerism. Molecular shape variations lead to distinct arrays, affecting intermolecular interactions and void volumes, influencing the macrostructure and resulting in different vapochromic behaviors.
