Synthesis, structure, and photoluminescence properties of 4-methyl- N-{2-([1-alkyl-2-[2-( p-tolylsulfonylamino)phenyl]benzimidazol-5-yl]iminomethyl)phenyl}benzenesulfonamides and their zinc complexes.

4-Methyl- N-{2-([1-alkyl-2-[2-( p-tolylsulfonylamino)phenyl]benzimidazol-5-yl]iminomethyl)phenyl}-benzenesulfamides (HL) and zinc complexes on their basis ZnL have been synthesized. The structure of the ligands and complexes has been studied by IR, UV, Н NMR spectroscopy, X-ray absorption spectroscopy, and X-ray diffraction analysis. [ABSTRACT FROM AUTHOR]
