Triphenylamine-based fluorophores containing pyrene or corannulene show variable fluorescence quenching sensitivity toward nitro explosives. The most sensitive fluorophore is capable of detecting TNT on the ng cm−2 scale; the array is useful for identifying nitro aromatics.

di-tert-butyl ester tripyrrane with TFA cleaved the protective groups, and subsequent condensation with diformylpyrroles in TFA-CH2Cl2, followed by oxidation with DDQ or ferric chloride, gave excellent yields of corannulenoporphyrins. Nickel(II), copper(II), and zinccomplexes of this system were also prepared, and the nickel derivative was also further characterized by X-ray crystallography. The same synthetic

In this study, we explore the potential of copper(I)-catalyzed cycloaddition reaction between azides and terminal alkynes to prepare corannulene-rich materials. For this purpose, a practical route is established to yield corannulene-based azide building blocks. The newly prepared corannulene-azides are then coupled with known corannulene-alkynes. The chemical yields of the dimerization reactions ranged from 80 to 90%. In this way, a number of triazole-linked corannulene derivatives varying in the geometry, length, and the triazole-content are prepared. These results suggest that alkyne-azide click reaction can serve as a useful synthetic tool in the preparation of corannulene-rich discrete oligomers as well as polymers. (C) 2012 Elsevier Ltd.
