Abstract: | An efficient cyclization toward a cyclic tetramer of dithienothiophene (DTT) linked by divalent selenium atoms has been developed via palladium‐catalyzed coupling reaction of (nBu3Sn)2Se. X‐ray analysis revealed its highly symmetrical structure had an alternate arrangement of DTT units. There are several Se???π interactions forming a supramolecular network leading to large void channel space. The cyclic tetramer possesses moderate electron‐donating ability. Furthermore, the cyclic tetramer undergoes complexation with C60 in a 1:2 ratio in the solid state to give a highly symmetrical three‐dimensional array of C60. |
