Multifunctional imidazobenzothiadiazole-based platform for halochromism, stimuli-responsiveness and optical waveguiding

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 o...
