SUMOF-3 microcrystals with controllable morphology and size were successfully obtained by solvothermal method and characterized by powder X-ray diffraction (PXRD), field emission scanning electron microscopy (SEM), thermogravimetric analysis (TGA), infrared (IR) and gas adsorption measurements. The influence of additives of polyvinylpyrrolidone (PVP), cetyltrimethylammonium bromide (CTAB), aqueous ammonia (NH3 center dot H2O) and triethylamine (TEA) on morphology and size of SUMOF-3 microcrystals was investigated, and the formation mechanism of the resulting crystal morphology was supposed. The results show that the surfactant of PVP and CAB as capping agent can affect the coordination interaction between the metal ion and organic linker, while the base of NH3 center dot H2O and TEA as modulator can affect deprotonation of the organic linker, resulting in the formation of SUMOF-3 microcrystals with controllable morphology and size. The results of gas adsorption measurements reveal that the crystalline particles have large surface area and pore volume, implying potential application in the fields of gas adsorption.
