چكيده فارسي :
Metal-organic frameworks are a class of attractive materials for fluorescent sensing. In this research, a two-fold interpenetration pillared-layer amine/imine-functionalized MOF known as TMU-16-NH2, [Zn2(NH2-BDC)2(4-bpdh)]·3DMF, have been synthesized via a mixed ligand approach using amino-1,4-benzenedicarboxylate (NH2-BDC) and 2,5-bis(4-pyridyl)-3,4-diaza-2,4-hexadiene (4-bpdh) under solvothermal condition. Sensor TMU-16-NH2 exhibits Al3+-selective TURN-ON and Fe3+-selective TURN-OFF type fluorescence emission responses, for which the electrostatic interaction between Fe3+ and Al3+ ions and the inner surface of the micropores may play a critical role.
