由于我国海岸线漫长、地形复杂，因长期地理隔离和生境不同，导致不同海域的文蛤在壳表形态和颜色、花纹图案等外观特征上均存在显著差异；另外，从多年的养殖实践中也发现，我国文蛤不同地理群体在生长速度、壳肉重比率等重要经济性状上也存在着显著差异，而这些性状的稳定性差异必然依赖于其分子遗传结构的变异。

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.
