Abstract

Simple thermal treatment of three-dimensional Kagomé-like [In(OH)(BDC)]n (In-MIL-68) hexagonal lumps in the presence of an extra amount of 1,4-benzenedicarboxylic acid (H2BDC) induces structural and morphological transformations of the hexagonal lumps into three-dimensional quartz-structured [InH(BDC)2]n (QMOF-2) pointed hexagonal rods. Transformation processes have been monitored by scanning electron microscopy to verify the destruction of the In-MIL-68-based hexagonal lumps and the simultaneous reconstruction of QMOF-2-based pointed hexagonal rods. We have also discovered the production of In-MIL-68-based hexagonal wires as early-stage kinetic products and the generation of QMOF-2-based pointed hexagonal rods as final-stage thermodynamic products from one-step solvothermal reaction of In(NO3)3 with an excess amount of H2BDC. Simple thermal treatment of In-MIL-68-based three-dimensional Kagomé-like structured hexagonal lumps in the presence of an excess amount of 1,4-benzenedicarboxylic acid (H2BDC) induces structural and morphological transformations into quartz-structured QMOF-2-based pointed hexagonal rods.
