摘要
Porous materials have been extensively developed and displayed special applications in diverse fields,however,it still remains a great challenge in developing new synthetic methods with features of energy-saving and easy-operating.In this study,we reported the construction of a series of novel ionic complexes based on discrete supramolecular triangle structure and polyoxometalate[Mo_(6)O_(19)]^(2-),using a quite efficient strategy.The obtained composites exhibit precise 3D network structures with ideal stability con-taining micropores,which were characterized by the 1H NMR,ESI-MS,TEM,SEM,and single-crystal X-ray diffraction.These compo-sites showed differential vapor adsorption behaviors for benzene,toluene,and cyclohexane.This work provides a novel approach for fabricating porous materials through electrostatic interactions and has great potential for gas separation.
