TTF, BTPおよびTCNE系合成の最近の展開

抄録

According to a system of classification for multi-stage redox systems proposed by Hünig, tetrathiafulvalene (TTF), bithiopyranylidene (BTP) are considered to be Weitz-type donors whereas tetracyanoquinodimethane (TCNQ) is regarded as Wurster-type acceptor. Recent efforts to explore new redox systems have provided various structural modifications, such as symmetrical, unsymmetrical, condensed, and inserted versions on TTF, BTP, and TCNE. In this review recent progress in design and synthesis of the modified TTF, BTP, and TCNE systems is described.
