Synthesis and photophysical studies of a new benzimidazole derivative and its zinc(II) complexes
The photochemical and photophysical properties of the new ligand N-[2-(5,6-dihydrobenzimidazo[1,2-c]quinazoline-6-yl)phenyl]-4-methylbenzolsulfamide (1) and its zinc complexes, namely [2-[(E)-[2-(1H-benzimidazol-2-yl)phenyl]iminomethyl]-N-(p-tolylsulfonyl)anilino]chloro-zinc (3) and acetoxy-[2-[(E)-[2-(1H-benzimidazol-2-yl)phenyl]iminomethyl]-N-(p-tolylsulfonyl)anilino]zinc (4) were studied using UV spectroscopy, time-resolved luminescence and stationary photolysis. Compound 1 combines the properties of Schiff bases and benzimidazole derivatives, both known as good luminophores. The structures of compounds in the crystalline state were determined by means of XRD. Ligand 1 demonstrates high photoluminescence quantum yields (PLQY) in solutions, while for the soluble zinc complex 3 it drops in an order of magnitude. PLQY in the solid state for all the compounds are moderate (0.2–0.3). For complex 3 the PLQY in the solid state is ca. 3 times higher than in solutions, demonstrating the effect of aggregation-induced enhancement of luminescence. The approach based on combining properties of the two classes of luminophores seems prospective for further development of luminescent materials.
期刊介绍:
The purpose of the Journal of Luminescence is to provide a means of communication between scientists in different disciplines who share a common interest in the electronic excited states of molecular, ionic and covalent systems, whether crystalline, amorphous, or liquid.
We invite original papers and reviews on such subjects as: exciton and polariton dynamics, dynamics of localized excited states, energy and charge transport in ordered and disordered systems, radiative and non-radiative recombination, relaxation processes, vibronic interactions in electronic excited states, photochemistry in condensed systems, excited state resonance, double resonance, spin dynamics, selective excitation spectroscopy, hole burning, coherent processes in excited states, (e.g. coherent optical transients, photon echoes, transient gratings), multiphoton processes, optical bistability, photochromism, and new techniques for the study of excited states. This list is not intended to be exhaustive. Papers in the traditional areas of optical spectroscopy (absorption, MCD, luminescence, Raman scattering) are welcome. Papers on applications (phosphors, scintillators, electro- and cathodo-luminescence, radiography, bioimaging, solar energy, energy conversion, etc.) are also welcome if they present results of scientific, rather than only technological interest. However, papers containing purely theoretical results, not related to phenomena in the excited states, as well as papers using luminescence spectroscopy to perform routine analytical chemistry or biochemistry procedures, are outside the scope of the journal. Some exceptions will be possible at the discretion of the editors.
