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.
Strained phenylacetylene macrocycles, cyclic [3]- and [4]metaphenylacetylenes ([n]CMPAs) and methoxy derivatives, and cyclic [5]- to [9]paraphenylacetylenes ([n]CPPAs) were prepared using a strategy based on the McMurry coupling reaction. The phys...

The pi-pi interaction between curved conjugated systems is important for the formation and properties of new carbon materials such as carbon nanotubes, bucky onions and fullerene peapods. However, the nature has been little understood so far. Rece...
The extended-qui none derivative of cyclopent[fg]acenaphthylene-1,2-dione (pyracyloquinone) is first synthesized and characterized. An X-ray analysis exhibits the non-planar structure involving bent of two 3,5-di-tert-butyl-4-oxo-cyclohexadienylid...
