Multifunctionalization of carbon nanohorns (CNHs) is easily achieved by microwave activation. We describe an efficient strategy to produce multifunctionalized CNHs using a combination of two different addition reactions, the 1,3-dipolar cycloaddition of azomethine ylides, in solvent-free conditions, and the addition of diazonium salts in water, both via a simple and fast microwave-induced method. The new CNH derivatives are soluble in common solvents as well as in water. The doubly functionalized CNHs may be valuable new tools for many interesting applications.

Abstract
Multifunctionalization of carbon nanohorns (CNHs) is easily achieved by microwave activation. We describe an efficient strategy to produce multifunctionalized CNHs using a combination of two different addition reactions, the 1,3-dipolar cycloaddition of azomethine ylides, in solvent-free conditions, and the addition of diazonium salts in water, both via a simple and fast microwave-induced method. The new CNH derivatives are soluble in common solvents as well as in water. The doubly functionalized CNHs may be valuable new tools for many interesting applications.
