Supramolecular complexation of C₆₀ and C₇₀ by helical nanographene incorporating <i>N</i>-heterotriangulene and hexabenzocoronene subunits.

ABSTRACT: Supramolecular host-guest complexes are studied in the gas-phase evaluating a new host molecule for fullerenes (C₆₀ and C₇₀). The new host molecule is a double N-heterotriangulene-[5]helicene (NTH), consisting of two N-heterotriangulene (N-HTA) blades embedded into a hexabenzocoronene-like backbone with helically curved topology. Host-guest complexes of [1:1]⁺˙^/2+, [1:2]⁺˙^/2+, [2:1]²⁺ and [2:3]²⁺ stoichiometry and charge state are formed by electrospray ionization-mass spectrometry (ESI-MS). Ion formation occurs through electrochemical oxidation of the N-HTA moieties. Energy-resolved collision-induced dissociation (ER-CID) experiments reveal the noncovalent binding of the ful
