Abstract:

Two newly prepared oligothienylpyridines, 5-(2-pyridyl)-5'-dodecyl-2,2'-bithiophene, HL2, and 5-(2-pyridyl)-5 `'-dodecyl-2,2':5',2 `'-ter-thiophene, HL3, bind to platinum(II) and iridium(III) as N boolean AND C-coordinating ligands, cyclometallating at position C-4 in the thiophene ring adjacent to the pyridine, leaving a chain of either one or two pendent thiophenes. The synthesis of complexes of the form {[}PtLn(acac)] and {[}Ir(L-n)(2)(acac)] (n = 2 or 3) is described. The absorption and luminescence properties of these four new complexes are compared with the behavior of the known complexes {[}PtL1(acac)] and {[}Ir(L-1)(2)(acac)] \{HL1 = 2-(2-thienyl)pyridine\
