Speaker: Prof Banglin Chen

Discoveries of novel multifunctional materials have played very important roles to the development of science and technologies and thus to benefit our daily life. Among the diverse materials, metal–organic framework (MOF) materials are rapidly emerging as a unique type of porous and organic/inorganic hybrid materials which can be simply self-assembled from their corresponding inorganic metal ions/clusters with organic linkers, and can be straightforwardly characterized by various analytical methods. They exhibit great potentials for a broad range of applications in gas storage, gas separations, enantioselective separations, heterogeneous catalysis, chemical sensing and drug delivery.

In this seminar, I will brief overview the history of MOF chemistry, and then describe our approaches on pore and function engineering to develop multifunctional MOF materials. We have been able to tune and optimize pore spaces, immobilize specific functional groups, and introduce chiral pore environments to target MOF materials for hydrogen, acetylene and methane storage, light hydrocarbon separations, enantioselective recognitions, carbon dioxide capture and separations. The intrinsic optical and photonic properties of metal ions and organic ligands, and guest molecules and/or ions can be collaboratively assembled and/or encapsulated into their frameworks, so we have realized a series of novel MOF materials as luminescent sensors, ratiometric luminescent thermometers, nonlinear optical materials, two-photon/two-photon pumped lasing materials, and two-photon responsive materials for 3D patterning and data storage. Some representative examples of MOFs and MOF composites for heterogeneous catalysis, membrane separations and proton conduction together with our ongoing research on porous hydrogen bonded organic frameworks (HOFs) will be also briefly presented.

Thanks to the interplay of the dual functionalities of metal–organic frameworks (the inherent porosity, and the intrinsic physical and chemical properties of inorganic and organic building blocks and encapsulated guest species), our research efforts have led to the development of multifunctional MOF materials beyond our initial imaginations.
