A Multifunctional 3D Ferroelectric and NLO-Active Porous Metal-Organic Framework

摘要

The construction of porous metal-organic frameworks (MOFs) is of great interest due to their potential applications in host-guest molecular interactions, catalysis, gas storage, and separation. One of current efforts focuses on introducing additional functionalities into porous MOFs, for instance, porous MOF based magnets. Since the discovery in 1920, ferroelectric materials have demonstrated remarkable utility in microwave devices, semiconductor chips, and miniature X-ray and neutron sources. Notably, ferroelectric complexes are increasingly attractrive in the assembly of predesigned organic spacers. On the other hand, second-order nonlinear optical (NLO) materials have also undergone rapid development owing to the versatile applicability of optoelectronic devices and photonics technologies. Hence, incorporation of both ferroelectric and second-order NLO properties into porous MOFs may lead to novel multifunctionality in the resultant materials.
