- Deprotonation- and TICT-triggered ultra-large Stokes shift of aqueous NIR-emissive hydroxylstryryl-pyridinium derivatives. Lu, Xiaolong Xiong, Liyu Zhang, Zhihan Yang, Haolong Li, Enmin Zhang, Hefeng Hydroxystyryl-pyridinium derivatives serving as fluorescent dyes with water-soluble conjugated skeletons exhibited remarkably large Stokes shifts of up to 404 nm and tunable deep-red to near-infrared (NIR) emissions, which are attributed to the enhanced charge transferring triggered by excited-state deprotonation of the phenol group and twist intramolecular charge transfer.
