Thioindigo precursor: control of polymorph of thioindigo
摘要:
2,2'-Bi[-3(2H)-thioplienon]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 P2(1)/c structure which was different from the commercial thioindigo samples (P2(1)/n). (C) 2004 Elsevier Ltd. All rights reserved.
