Designing the architecture of donor–acceptor (D–A) pairs is an effective strategy to tailor electronic structure conjugated macrocycles for optoelectronic devices. Herein, we present synthesis three D–A nanohoops NDI-[n]CPP (n = 7, 8, 9) containing a naphthalene diimide (NDI) unit as acceptor and [n]cycloparaphenylenes ([n]CPPs) moieties donors. The characteristics NDI-[7–9]CPPs were substantiated through absorption fluorescence spectroscopic studies, electrochemical investigations, computational analysis. device investigations demonstrated that can serve photoconductive layer demonstrate significant generation photocurrent with fast response upon exposure light. magnitude shows high dependence on size their rings, increasing tendency ring decreases. in free acceptor-based CPP has rarely been reported previous literature. Significantly, C60 complexes exhibited marked enhancement under identical conditions; particular, C60⊂NDI-[7]CPP ca. 3.5 times greater than NDI-[7]CPP alone. Furthermore, potential applications electron- hole-transport devices have also explored, revealing clear evidence bipolar behavior active charge transport layer.

Radially π-conjugated macrocycles with mixed aromatic and quinonoid units are considered. As a function of including an increasing number into ring-like nanohoop units, transition occurs where the HOMO LUMO levels cross, leading to topological described for first time. Such transitions have been seen before in ethynylene-linked oligoacene polymers as acene size on gold surfaces various external strain, but not small molecular nanohoops or any other zero-dimensional system. Near level crossing, HOMO-LUMO gap becomes very small, offering novel photophysical properties while maintaining extensive delocalization. The open shell character rings changes continuously composition is gradually changed, switching from singlet ground state triplet, providing analogy between non-trivial trivial phase observed linear one-dimensional conjugated polymers. spins triplet localized near two aromatic-quinonoid connections.
