ABSTRACT:
Novel organic heat-sensitive semiconductive materials containing tetracyanoquinodimethane (TCNQ) as electron acceptor and exhibiting inherent resistivity-temperature characteristics. The materials include (N-n-propylthiazolium).sup.+ (TCNQ).sup.- (TCNQ), (N-n-butylthiazolium).sup.+ (TCNQ).sup.- (TCNQ) and(N-n-butyl pyridinium).sup.+ (TCNQ).sup.- (TCNQ). These three compounds can be prepared by reacting TCNQ with iodides of corresponding cations, respectively. The heat-sensitive materials have particular utility in the field of timing or heat-sensitive elements.
