TTFs in Cross-Conjugated Systems

Acetylene-Extended Tetrathiafulvalenes in Cross-Conjugated Systems 

Apart from this study, there has been growing interest in cross-conjugated systems containing diethynylethene (DEE) with several DT rings because of potential applications for various optical properties as well as two-dimensional it-conjugation network [63-65]. There is a wealth of research publications about diacetylene-extended cross-conjugated systems we briefly summarize selected examples in this section [66-70]. 

The Y-shaped l,3-dithiole-2-ylidene unit, inserted into an acetylene scaffold, was also utilized as a building block for a two-dimensional network in crystals. Yamashita and coworkers [71] have constructed the cross-conjugated system 71
