Solid state reactivity, inorganic nanomaterials and metal-organic framework (MOF) materials. Current interests include solid-state reactivity, photochemistry and structural transformations, gels and fibers & energy storage materials. Currently we are interested in designing multifunctional materials showing multi-photon absorption, second harmonic generation (SHG) and third harmonic generation (THG) properties, and creating non-centrosymmetry via defects in CPs and MOFs.
This figure depicts a centrosymmetric 1-D coordination polymer showing SHG, THG and multo-photon-excited photo-luminescence depending on the excitation wavelength used. Ref: J. Mater. Chem. C, 2017, 5, 2936.
By changing the position of the fluoro substitution in the ligand and modifying the crystallization conditions, Zn(II) complexes have been shown to exhibit [2+2] photocycloaddition reactions, mechanical motion under UV light and curved single crystals have been obtained. Ref: IUCrJ, 2017, 4, 65-71.
