New classes of nonlinear polyaromatics with extended conjugation at lateral and longitudinal directions from triphenylene, tetracene, and pentacene backbones are reported. These planar and twisted polyfused aromatics are obtained through specific and selective multifold Scholl reactions from predesigned polyaryls. These derivatives displayed shifted or perfect cofacial packing motifs. Single crystals of one derivative, phenanthro[9,10:b]triphenylene, were used as p-channel materials in fabricating transistor devices, which exhibited an average mobility of 0.38 cm(2) s(-1) and a maximum mobility reaching 1.15 cm(2) V-1 s(-1)
