Millimeter-Scale Zn(3-ptz)₂ Metal-Organic Framework Single Crystals: Self-Assembly Mechanism and Growth Kinetics.

ABSTRACT: The solvothermal synthesis of metal-organic frameworks (MOFs) often proceeds through competing crystallization pathways, and only partial control over the crystal nucleation and growth rates is possible. It challenges the use of MOFs as functional devices in free-space optics, where bulk single crystals of millimeter dimensions and high optical quality are needed. We develop a synthetic protocol to control the solvothermal growth of the MOF [Zn(3-ptz)₂] _n (MIRO-101), to obtain large single crystals with projected surface areas of up to 25 mm² in 24 h, in a single reaction with in situ ligand formation. No additional cooling and growth steps are necessary. We propose a viable reaction mechanism for the formation of MIRO-101 crystals under acidic condi
