| Sumario: | In this work, we report the rational design, synthesis, and characterization of a multifunctional platform based on an imidazobenzothiadiazole (IBT) core, integratinghalochromic behavior, stimuli-responsiveness, and potential applications as optical waveguides. The IBT derivative exhibits distinct optical changes upon exposure toacidic and basic vapors, enabling precise halochromic sensing. Its molecular structure, tailored through rational engineering of the IBT scaffold and triphenylamine(TPA) group, also imparts reversible responsiveness to external stimuli, modulating emission properties. Photophysical studies also reveal high fluorescence quantumyields. Furthermore, the compound demonstrates efficient guided emission and optical waveguiding along interconnected emissive aggregates in red colour correspondingto wavelengths near to the NIR region, highlighting its potential as a high-performance light-transmitting material for next-generation optoelectronicdevices. Altogether, these features position this IBT-based system as a promising example of a truly multifunctional molecular platform, bridging sensing, stimuliadaptablebehavior, and photonic integration, and opening new horizons in advanced materials science. |
