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.

Treatment of 2,6-di-tert-butyl-4-ethynylphenol with 2 equivalents of nBuLi, followed by addition of diaryl ketones, afforded the corresponding p-quinopropadienes 2a-f upon appropriate dehydrative treatments. These compounds are fairly stable, oran...
