三聚茚（英語：Truxene）是一種多環芳香烴，該分子可被認為是由三個對稱排列並共享一個中心苯的芴組成。三聚茚是一種固體，微溶於水。

歷史

自19世紀末以來，三聚茚就為人所知。J. Hausmann於1889年在研究3-苯基丙酸與五氧化二磷的反應時偶然發現了它。他無法確定確切的結構，但假設它是1-茚满酮的環狀三聚體。據他介紹，它是由3-苯基丙酸分子內酰化產生的1-茚满酮縮合而成。^[2]

弗里德里克·基平（英语：Frederic Kipping）於1894年確定了三聚茚的結構，並通過1-茚满酮的三聚反應獲得了該化合物。^[3]

製備

三聚茚通過在乙酸和濃鹽酸的混合物中，由1-茚满酮的循環三聚合製備。^[4]

用途

三聚茚具有星形，因此適合作為樹狀物合成的起點。^[5]

三聚茚的衍生物也已用於合成液晶^[6]和富勒烯的片段。^[7]
