An “annealing-free” strategy consisting of using a planar nickel bisdithiolene complex nickel bis[1,2-di(3′,4′-di-n-decyloxyphenyl)ethene-1,2-dithiolene] ([Ni(4dopedt)2]) is proposed for structuring poly(3-hexyl-thiophene) (P3HT). Photoluminescence (PL) and Raman spectroscopies, in conjunction with electronic absorption, have been used for evidencing P3HT changes due to blending. PL and absorption observations are consistent and show a correlation between polymer chain organization and increasing amounts of [Ni(4dopedt)2]. Blending with [Ni(4dopedt)2] do not modify the Raman ring-breathing modes energies indicating that blending does not induce strongly disorder in P3HT chains. Atomic force microscopic measurements show that blends nanoscale morphology presents a homogeneous matrix and small fibrils related to [Ni(4dopedt)2] concentration, especially for blends with a [Ni(4dopedt)2] weight ratio lower than 50%.
