title: Dramatic enhancement of carrier mobility via effective secondary structural arrangement resulting from the substituents in a porphyrin transistor.
abstract: OFET devices based on single-crystals of two different porphyrin derivatives display excellent mobilities of 2.57 and 0.48 cm(2) V(-1) s(-1). Although they generate similar J-aggregations, the dramatic enhancement of mobility obtained using porphyrin 1 is due to the well-confined secondary structural arrangement caused by substituents on the porphyrin ring.
