In the paper, the multidentate carboxylic acid ligands were used to combine with Cd, resulting in the three dimensional MOCPs single crystals—C12H16CdN2O8, with a low temperature hydrothermal synthesis method. The sample was characterized with IR spectra to affirm the organic groups in the frameworks, single-crystal X-ray diffraction to determine the crystal structure and composition of the frameworks, N2 adsorption isotherms at low temperature to measure the specific surface area and pore size distribution, and with TGA/DGA analysis to scale the thermal stability. Furthermore, the dissolution property and the photocatalytic activity of MOCPs under the ultraviolet ray condition were explored.

Many nanotwins were formed in this triangular region. HREM observations showed that nanotwinning dislocations were nucleated at noncoherent twin boundaries with the local stress concentration, and the nucleation is related to the dislocation dissociations at the boundary ledges. The proceeding of these nanotwins is the homogenous shears of 1/6 [11〓] twinning dislocations, which is that the trailing 1/6 [112] twinning dislocations repel the leading twinning dislocations to proceed in the (111) planes. Therefore, twinning dislocations at the twin tip appear to be on one side of twin, forming a noncoherent twin boundary with a semilenticular shape.
