Abstract
A cyclic ethylene linked triphenylamine dimer formed highly crystalline thin film via vapor deposition. Meanwhile, the corresponding linear molecule only resulted in amorphous films under the same condition. The performance as FET semiconductor also improved significantly when the molecular structure derived from linear to cyclic type. The cyclic molecule displayed mobilities in excess of 10-2 cm2 V-1 s-1 and high on/off ratios up to 107.Keywords
