We report the use of a tetraborylated perylenediimide as starting material for the preparation of a tetracorannulene-perylenediimide that is able to bind up to two fullerene-C60 molecules by host–guest molecular recognition with preference over C70. Titration with fullerene-C60 is followed by a dramatic shift of the aromatic signals in 1H NMR and an initial increase in the fluorescence of the system. By this simple mechanism, fluorogenic sensing of fullerene-C60 is easily accomplished by an unprecedented fluorescent turn-on mechanism.

PGM. EGDMA was used as cross-linking agent (Scheme 1). 63The comonomer molar ratio 2HEA/PGM/EGDMA was 64 95/5/5, respectively. 2,2-Dimethoxy-2-phenylacetophenone 65 (DMPA, 1.5 wt %) was employed as a photochemical initiator. 66The photoinitiated bulk polymerization was performed in a 100 67 μm thick silanized glass hermetic mold upon irradiation with a
