资源简介：
Two amino-functional
copper metal–organic frameworks of
formula [Cu3(ATTCA)2(H2O)3]·2DMF·11H2O·12EtOH (1) (H3ATTCA = 2-amino-[1,1:3,1-terphenyl]-4,4,5-tricarboxylic
acid, pyz = pyrazine, DMF = dimethylformamide) and [Cu3(ATTCA)2(pyz)(H2O)]·2DMF·12H2O·8EtOH (2) were synthesized under solvothermal
conditions and characterized by single-crystal X-ray diffraction,
infrared spectroscopy, elemental analyses, thermogravimetric analyses,
and powder X-ray diffraction. Single-crystal X-ray diffraction analysis
revealed that both complexes 1 and 2 are
built of the Cu2(COO)4 paddlewheel secondary
building units with an fmj topology.
Importantly, complex 1 can be transformed into complex 2 by the single-crystal to single-crystal transformation of
which the coordinated water molecules are replaced with pyz molecules.
However, the adsorption abilities of 2 are obviously
lower than those of 1, as its pores are partially blocked
by pyz molecules. Moreover, gas-adsorption analysis showed that the
amino-functional 1 possesses higher gas-adsorption capacity
than UMCM-151 for N2, H2, CH4, and
C2H2, especially for CO2.
