'''{{zy|苉|pǐ|ㄆㄧˇ|pat1}}'''（{{langx|en|Picene}}）是一种[[多环芳香烃]]，化学式C<sub>22</sub>H<sub>14</sub>，由泥炭焦油或石油蒸馏的残留物蒸馏至干，用[[对异丙基甲苯]]反复重结晶得到。

==性质==
苉为具有蓝色荧光的无色晶体，溶于浓硫酸溶液显绿色。在冰醋酸溶剂中用[[铬酸]]氧化苉得到苉醌，随着氧化继续进行稠环断裂形成羧酸，最终产物为[[邻苯二甲酸]]。苉晶体层间掺入钾或铷冷至18K以下时体现出[[超导性]]。.<ref>{{cite|last=Das|first=Saswato|title=Hydrocarbon Superconductor Discovered|journal=[[IEEE Spectrum]]|url=http://spectrum.ieee.org/energy/the-smarter-grid/hydrocarbon-superconductor-discovered|date=March 2010|accessdate=2013-07-16|archive-date=2017-09-19|archive-url=https://web.archive.org/web/20170919005709/https://spectrum.ieee.org/energy/the-smarter-grid/hydrocarbon-superconductor-discovered|dead-url=no}}</ref>
