In the last 13 years several synthetic strategies were developed that provide access to [n]cycloparaphenylenes ([n]CPPs) and related conjugated nanohoops. A number of potential applications emerged, including optoelectronic devices, and their use as templates for carbon nanomaterials and in supramolecular chemistry. To tune the structural or optoelectronic properties of carbon nanohoops beyond the size-dependent effect known for [n]CPPs, a variety of aromatic rings other than benzene were introduced. In this Review, we provide an overview of the syntheses, properties, and applications of conjugated nanohoops beyond [n]CPPs with intrinsic donor/acceptor structure or such that contain acceptor, donor, heteroaromatic or polycyclic aromatic units within the hoop as well as conjugated nanobelts.
在过去的13年里，人们开发了几种合成策略，可用于制备[n]环对亚苯基（[n]CPPs）及相关的共轭纳米环。由此出现了许多潜在应用，包括光电器件，以及它们作为碳纳米材料的模板和在超分子化学中的应用。为了超越[n]CPPs已知的尺寸依赖效应来调节碳纳米环的结构或光电性质，人们引入了除苯以外的各种芳环。在本综述中，我们概述了具有固有供体/受体结构或在环内包含受体、供体、杂芳族或多环芳族单元的[n]CPPs以外的共轭纳米环以及共轭纳米带的合成、性质和应用。
