| Popis: | We have synthesized a series of aza[8]cycloparaphenylenes containing one, two, and three nitrogens to probe the impact of nitrogen doping on optoelectronic properties and solid state packing. Alkylation of these azananohoops afforded the first donor–acceptor nanohoops where the phenylene backbone acts as the donor and the pyridinium units act as the acceptor. The impact on the optoelectronic properties was then studied experimentally and computationally to provide new insight into the effect of functionalization on nanohoops properties. We have developed the synthesis of aza[8]cycloparaphenylenes containing one, two, and three nitrogens to probe the impact of nitrogen-doping on optical and electronic properties, as well as solid-state packing. Alkylation of these aza-nanohoops afforded donor−acceptor nanohoops where the phenylene backbone acts as the donor and the pyridinium unit acts as the acceptor. The impact on the optical and electronic properties was then studied experimentally and computationally to provide new insight into the important design features of these and future donor−acceptor nanohoops. |
