Abstract
One-dimensional nanomaterials, PVP (poly(vinylpyrrolidone)) fibers doped with [Ru(Bphen)2dppz]Cl2 (Bphen = 4,7-diphenyl-1,10-phenanthroline; dppz = dipyrido[3,2-a:2′,3′-c]phenazine) were prepared by electrospinning technique. The luminescent properties of the composite fibers with diameters between 500 and 900 nm were investigated. Bright red emission centering at 596 nm attributed to the metal (dπ) to ligand (π*) charge-transfer (3MLCT) transition was observed. The composite fibers doped 0.20 wt.% ruthenium(II) complex were optimal, which exhibited the maximum luminescent intensity.
