Three new members of N-heteropentacenes explored herein have adjacent pyrazine and dihydropyrazine rings at one end of the pentacene backbone. Interesting findings from this study include self-complementary N鈥揌路路路N H-bonds in the solid state, solvent-dependent UV鈥搗is absorption caused by H-bonding, and new p-type organic semiconductors with field effect mobility up to 0.7 cm2 V鈥? s鈥?.
