Linear Optical Absorption, Emission Properties and Ultrafast Carrier Dynamics of Aqua-chloro-bis(1,10-phenanthroline)manganese(II) 4-formylbenzoate Trihydrate

Abstract

In this study, the synthesis, Hirshfield surface analysis, linear absorption, fluorescence properties and carrier dynamics of [Mn(1,10-phenanthroline)(2)(H2O)Cl].(4-formylbenzoate)(H2O)(3) complex were reported. To determine of the structure the complex, elemental analysis, FT-IR Spectra, and single crystal X-ray diffraction analysis were done. The linear optical absorption and emission measurements of the complex in DMSO solvent at 0.5 g/L concentration were recorded by UV-Vis and fluorescence spectrophotometers, respectively. The carrier dynamics of the complex was obtained by using time-resolved transmission pump-probe spectroscopy. In the light of the obtained optical results, it can be said that the complex is linear optically ultraviolet absorber, nonlinear optically excited state absorber and wide range emitter with fast response time. The intermolecular interactions which are occurred in the complex were investigated by Hirshfeld surface analysis. Three dimensional d(norm) and two dimensional fingerprints plots of the complex were obtained from Hirshfeld surface analysis. In this way, the amounts of the chemical bounds, taking place in the structure were determined and used to support of the discussion of the linear optical absorption and emission results which were experimentally obtained.
