Synthesis, characterization, optical absorption/fluorescence spectroscopy, and second-order nonlinear optical properties of aggregate molecular architectures of unsymmetrical Schiff-base zinc(II) complexes / I.P. Oliveri, S. Failla, A. Colombo, C. Dragonetti, S. Righetto, S. Di Bella. - In: DALTON TRANSACTIONS. - ISSN 1477-9226. - 43:5(2014), pp. 2168-2175. [10.1039/C3DT53072H]
Abstract:
This paper reports the synthesis and a detailed investigation in solution, through 1H NMR, optical absorption, fluorescence spectroscopy and second-order nonlinear optical studies, on the structure and photophysical properties of a series of unsymmetrical alkoxy-derivatized Schiff-base Zn II species bearing on one side an alkyl ammonium bromide as a Lewis base. Overall results suggest that these complexes are present in solution of dichloromethane as dimeric aggregates in which each molecular unit mutually interacts with another unit through intermolecular Zn⋯Br- interactions. This represents an alternative approach to control the supramolecular architecture of Lewis acidic, Schiff-base ZnII complexes.
