N-di(isopropyl)phenyl-2-azaphenalenyl radical cations were obtained as a dark brown air-sensitive crystalline compound. The high HOMA values and the ACID calculation indicate relatively high aromatic character of a 5,8-di-tert-butyl derivative, an...
We report the synthesis of P-BT and TP-BT and their OTFT properties based on electronic dimensionality and access resistance (Racc). TP-BT can suppress Racc due to its 3D electronic structure.
The McMurry coupling of 2,7-diformylfluorene affords a dimer, anti-[2.2](2,7)-fluorenophanediene, and a trimer, [2.2.2](2,7)-fluorenophanetriene, as cyclic oligomers. X-Ray crystallography of the dimer establishes its strained, layered structure w...

Upon heating at 200 degreesC in o-dichlorobenzene, 2,5-bis(dicyanomethylene)bicyclo[4.2.0]octa-3,7-diene gave rise to 2,6-bis(dicyanomethylene)bicyclo[3.3.0]octa-3,7-diene by a rearrangement as a sole isolable product in modest yield, and no trace...

A dibenzo-ortho-terphenoquinone derivative, the first o-terquinone derivative, is largely deviated from coplanarity, is in a slight equilibrium with its diradical form, displays an easy rotation of the exocyclic double bonds, and shows photorespon...

The McMurry coupling of tris(5-formyl-2-thienyl)methane afforded an unsubstituted, etheno-bridged trithienylmethanophane which was in turn transformed to novel cage-molecular monocation, dication, and dianion of substantial stability. The latter t...
