1,1,n,n-Tetramethyl[n](2,11)teropyrenophanes (n = 7–9): a series of armchair SWCNT segments

A new iterative bridge formation strategy has been employed in the synthesis of a series of [n](2,11)teropyrenophanes (n = 7–9). The generation of the nonplanar teropyrene system, which is calculated to be bent through 178.7° for the smallest homologue (n = 7), is accomplished using a VID reaction of a cyclophanemonoene precursor for the first time.
