Additive-Induced Supramolecular and Structural Isomerism in Zn(II) MOFs: Tuning Emission from Intraligand Local Excitation to Intermolecular Charge Transfer through π-Stacking Control.
Additive-directed assembly is a powerful yet underexplored route to supramolecular isomers with tunable metal-organic framework (MOF) photophysics. Three Zn(II) MOFs, [Zn(Hbtzip)2(H2O)2]·4H2O (1), [Zn(Hbtzip)2(H2O)2] (2), and [Zn(btzip)] (3), were hydrothermally synthesized from 4,6-bis(triazol-1-yl)isophthalic acid (H...
