Abstract
Materials with non-linear optical (NLO) properties play an important role in the construction of electronic devices for optical communications, optical data processing and data storage. With this aim in mind, a Zn(II)-based metal-organic framework {[Zn2(nica)2(bpy)1.5(H2O)]·0.5(bpy)·3H2O}n (1), was synthesized using 4,4ʹ-bipyridine (bpy) and a potentially bidentate ligand, 2-hydroxynicotinic acid (H2nica) with a salicylate binding moiety. A single-crystal X-ray diffraction analysis revealed that compound 1 crystallized in the orthorhombic space group Fdd2 and was composed of a three dimensional porous framework. Since Fdd2 belonged to a class of non-centrosymmetric space groups, we therefore investigated the non-linear optical behaviour of compound 1. Photoluminescence studies revealed that compound 1 exhibited a blue light emission with a maxima at 457 nm.
Highlights
Metal-organic frameworks (MOFs) have gained considerable attention as a new type of multifunctional materials owing to their numerous real and potential applications in gas sorption, storage, chemical and biological detection, medical imaging and light emitting devices [1,2,3,4,5,6,7]
Compound 1 was synthesized from a mixture of Zn(NO3)2·6H2O, H2nica and bpy via a single-step, self-organization process (Scheme 2)
A number of Zn-based metal-organic frameworks and Schiff-base complexes have been investigated for their second order non-linear optical (NLO) properties [23,24,25,26]
Summary
Metal-organic frameworks (MOFs) have gained considerable attention as a new type of multifunctional materials owing to their numerous real and potential applications in gas sorption, storage, chemical and biological detection, medical imaging and light emitting devices [1,2,3,4,5,6,7]. These hybrid materials take advantage of the properties of both traditional inorganic and organic materials and comprise novel functional materials with a degree of structural predictability [8]. To the best of our knowledge, such non-linear optical behaviour and luminescence properties of such a coordination compound have never been previously explored
