A Pyrene-Embedded Molecular Nanotube with Donor–Acceptor Properties
Shape-persistent pyrene-embedded macrocycles remain scarce, and tubular conjugated molecules with intrinsic donor–acceptor (D–A) character have only recently emerged, largely within [n]cyclo-para-phenylene-based systems. Here we introduce a structurally distinct pyrene-containing nanotube (Pyr4), synthesized through...
