Yadav SK, Mahapatra SS, Yoo HJ, Cho JW - Nanoscale Res Lett (2011)

Bottom Line: A new hybrid material consisting of a polyhedral oligomeric silsesquioxane (POSS) and carbon nanotube (CNT) was synthesized by a simple and versatile approach entailing click coupling between azide moiety-functionalized POSS and alkyne-functionalized multi-walled CNTs.This approach provides a simple and convenient route to efficiently functionalize a wide variety of nanoscale nanostructure materials on the surface of CNTs.

Figure 1: Strategy for "clicking" POSS molecule onto MWNTs.

Mentions: The azidation of the POSS molecule was carried out with sodium azide in the presence of ammonium chloride, as shown in Figure 1. Typically, a solution of POSS (1.0 g 3.19 mmol) in tetrahydrofuran (THF) (5 ml) was added to a solution of sodium azide (208 mg 3.19 mmol) and ammonium chloride (170 mg 3.18 mmol) in DMF (5 ml), and the mixture was stirred for 35 h at 50°C. The mixture was precipitated into 200 ml of water and the product was vacuum dried at 40°C for 60 h. The yield of azide-functionalized POSS obtained was 85%.
