SUPRAMOLECULAR ARCHITECTURE AND PHOTOPHYSICAL AND BIOLOGICAL PROPERTIES OF RUTHENIUM(II) POLYPYRIDYL COMPLEXES

Abstract

Complexes of the type [Ru(N–N)2(tdzp)]Cl2, where N–N is 2,20 -bipyridine (bpy) (1), 1,10-phenathroline (phen) (2), dipyrido[3,2-d:20 ,3-f] quinoxaline (dpq) (3), which incorporate the [1,2,5]-thiadiazolo-[3,4-f ]- [1,10]-phenanthroline (tdzp) ligand, have been synthesized and characterized by IR, 1 H-NMR, 13C-NMR, ESI-MS, elemental analysis, UV-Visible and luminescence spectroscopy. The molecular structure of complex 2 is confirmed by single crystal X-ray structure determination
