2,7-Diazatriptycene: Acid-Responsive Ternary Fluorescence Switching via Modulation of Through-Space Conjugation
Abstract
An unexplored 2,7-diazatriptycene exhibits protonation-controlled ternary fluorescence switching (on/off, cyan/violet) through modulation of through-space conjugation. Protonation also reorganizes crystal packing from herringbone assemblies to charge-segregated layered structures.
