Photoswitchable radicals incorporating dithienylethene (DTE) moieties offer unique opportunities for dynamic control in various chemical and material applications. By exploiting light-triggered isomerization processes, researchers can achieve precise modulation of radical reactivity, enabling spatiotemporal transformations. Despite growing interest this field, challenges remain controlling spin-orbit coupling spin dynamics, which influence the electronic structure transitions induced by light absorption as well achieving photostability repeated photoisomerization cycles. To address these challenges, we have designed a new family photoswitchable organic that incorporate DTE carbazole centers. We studied delocalization through molecular evolution upon irradiation using ultraviolet/visible absorption, electron paramagnetic resonance, nuclear magnetic resonance spectroscopies. Our findings demonstrate photochromic behavior neutral form reversible formation, contributing to advancements promising field.
