Abstract

Hydroxyl substituents direct the intrinsic excited-state intramolecular proton transfer (ESIPT) tautomerism of flavonoids, while substituent hydrophilicity-hydrophobicity and π-π interactions regulate their self-assembly, highlighting substituents' decisive role in flavonoid properties. Herein,...
