Dithieno benzene

More recently, OFETs were made with a dimer of another condensed molecule. dithieno[3,2-/j 2, 3 -c/ lhiophene 100, which presents a very similar structure lo that of benzodithiophene, except that the central benzene ring is changed lo a... 

Similarly, dithieno[l,2-A4,5-/) ]benzene 45 has completely planar molecular structures packed in a herringbone arrangement <2005JOC10569>. 

The phosphole ring can be fused to a number of other cyclic structures. The most widely found are the dibenzo- and dithieno-derivatives 9 and 10. It is noteworthy that these compounds display few properties associated with phospholes. Instead, they behave as diarylphosphines due to the presence of the highly aromatic fused benzene or thiophene rings. 

Racemate and mesomer forms of the interesting elaborated thiophene-based naphthalene-cored double helicenes 18 have been synthesized using a one-pot photocycUzation of l,l,2,2-tetrakis(dithieno[2,3-l 3 2 -[Pg.9]
