The study investigates a 40-hydroxyflavylium derivative with a julolidine substituent, revealing that it does not exhibit trans-cis chalcone photoisomerization in water and has a significantly lower fluorescence emission quantum yield compared to its non-rigid analog. These findings challenge the Twisted Intramolecular Charge Transfer (TICT) model as an explanation for the observed behaviors. The research also indicates that hydration of the flavylium cation occurs primarily at basic pH values, with proton
