We reports the synthetic route to crafting semiconducting organic-inorganic nanocomposites comprising conjugated polymers in intimate contact with inorganic nanocrystals (NCs) via a catalyst-free click reaction. It highlights simple, robust, yet effective sodium azide treatment to completely detach all the insulating aliphatic ligands including covalently bounded ones from NC surfaces as well as to introduce coupling agents, those are covalently bonded azide sites, onto NC surfaces, yielding azide-terminated NCs. Subsequently, ethynyl-terminated organics (e.g., 1-octyne and ethynyl-terminated poly(3-hexylthiophene) were tethered with azide-functionalized NCs via a catalyst-free alkyne-azide cycloaddition, yielding semiconducting organic-inorganic NC nanocomposites. The success of click reaction was substantiated by Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance spectroscopy (NMR) measurements. |
