Since the late seventies, the search for new molecular receptors has been constant in perfecting the affinity and selectivity of recognition in different media. At present, a renewed interest in (host:guest) chemistry focuses on the molecular detection of specific targets such as biological, pollutant, toxic or explosive species. This review of triphenylene-based receptors outlines their recent contribution to molecular recognition. Two main structural approaches were investigated to transform a simple triphenylene moiety into a host for neutral aromatic compounds or cations, by tailoring multivalent molecules provided with or without a flatten cavity. The properties of different receptors are presented along with the latest synthetic methods to prepare high-value triphenylenes and the perspectives in the field of sensing. In addition, the role of functionalized triphenylenes in extended (host:guest) systems is illustrated by the main examples of discotic liquid crystals and porous coordination polymers involving this polyaromatic compound.

自七十年代末以来，在完善不同介质中识别的亲和力和选择性方面，一直在寻找新的分子受体。目前，对（宿主：客体）化学的新兴趣集中在对特定目标（例如生物，污染物，有毒或爆炸性物种）的分子检测上。这项对基于三亚苯基的受体的综述概述了它们最近对分子识别的贡献。研究了两种主要的结构方法，即通过定制提供或不提供平坦腔体的多价分子，将简单的亚苯基部分转化为中性芳族化合物或阳离子的主体。介绍了不同受体的特性，以及用于制备高价值亚苯撑的最新合成方法，以及传感领域的观点。此外，
