A facile route to semiconductor nanocrystal-semiconducting polymer complex using amine-functionalized rod-coil triblock copolymer as multidentate ligand

A facile strategy affording an intimate nanocomplex of an amine-containing rod-coil triblock copolymer poly(2-(dimethylamino)ethylmethacrylate)- poly(fluorene)-poly(2-(dimethyl amino) ethylmethacrylate) and CdSe nanocrystals is presented. Ligand exchange is observed by ³¹P NMR. TEM and UV-vis absorption results indicate the CdSe NCs have a good dispersion in the conjugated polymer. Also, the PL spectra show photoinduced charge transfer has been facilitated by the complex formation.
