Abstract

Covalently interconnected single walled carbon nanotube (SWNT) networks have attracted a particular interest due to their enhanced accessible surface area. Herein, an elegant way of preparing covalently interconnected SWNTs is demonstrated for the first time via coupling reactions. Sonogashira and Ullmann coupling reactions offer a versatile route for the preparation of molecularly-bridged SWNTs (MBSWNTs). Couplings create C C bonds between SWNTs yielding MBSWNTs with conductive 1,2-diphenyl-diacetylene and biaryl bridges. Elemental composition analysis done by XPS shows the evidence of successful couplings while mass traces of the interconnected SWNTs corroborating with fragmentations corresponding to conjugated linkers.
