多氯双苯并对二𫫇英

多氯双苯二𫫇英一般结构键线图，注意此jargon图中支出的氯用于取代苯环上的氢而不是去与苯环中央的共振电子云去共享电子（那做不到）

多氯代双苯并对二𫫇英（polychlorinated dibenzo-p-dioxins）是对二𫫇英（对二𫫇己熳）衍生物中最重要、危害最大的一类，是二苯并对二𫫇英的氯代物，一般提到“二𫫇英”时指的均是对二𫫇英衍生物中的此一子类，包含臭名昭著的橙剂杂质2,3,7,8-四氯雙苯環二噁英（2,3,7,8-TCDD）。

化合物列表

二苯并对二𫫇英的取代位编号示意图，由于5位和10位被氧给杂了，至多可以有八个氢被代。在2,3,7,8上用四个氯取代即是著名的2,3,7,8-四氯雙苯環二噁英。

二苯并对二𫫇英含有两个苯环和两个氧桥，形成芳香二醚。命名中的“二𫫇”指

由于二苯并对二𫫇英的5位和10位被氧给杂了，至多可以有八个氢被代。存有凡75种多氯双苯并对二𫫇英的（不同分）异构体。
