Abstract
In this study, a new phenoxy cyclophosphazene derivative bis(2-formyl-phenyl)4,4,6,6-bis[spiro(2’,2”-dioxy-1’,1”biphenylyl)]cyclotriphosphazene (P2) was synthesis in by the reactions between 2,2-dichloro-4,4,6,6-bis[spiro(2’,2”-dioxy-1’,1”biphenylyl)]cyclotriphosphazene (P1) with salicyl aldehyde in presence of K2CO3 at room temperature in THF under argon atmosphere, and the new phenoxy cyclophosphazene derivative Schiff bases which are containing long-chain alkyl groups and salicyl aldehyde, bis[spiro(2’,2”-dioxy-1’,1”biphenylyl)2,3-diphenoxy-2-imidododesyl]cyclotriphosphazene (P3) synthesized by condensation reactions in suitable conditions with (P2) and dodecylamine. Synthesized ligands have been investigated with the methods of FTIR, 31P NMR, Uv-vis, MS spectroscopies, elemental and thermal analysis (TGA and DSC). Co(III), Ru(II) complexes were synthesized (L/M) 1:2 ratio and characterized FTIR, UV-vis and MS spectra, together with elemental and thermal analysis.
