The precursor was converted to thioindigo with P21/c structure by heating. 2,2′-Bi[-3(2H)-thiophenon]ylidene with two bicyclo[2.2.2]-octadiene moieties was quantitatively converted to thioindigo by the retro-Diels-Alder reaction. The thioindigo solid obtained from the precursor had the P21/c structure which was different from the commercial thioindigo samples (P21/n).
