## Abstract Photocyclization of 3‐chloro‐N‐(3‐phenanthryl)thieno[2,3‐__b__]thiophene‐2‐carboxamide (5) yielded only one of the two possible structural isomers, thieno[3′,2′:4,5]thieno[2,3‐__c__]naphtho[1,2‐__f__]quinolin‐6(5__H__)‐one (6), which was further elaborated to afford the unsubstituted ri
