TY - JOUR A1 - Pingel, Patrick A1 - Zen, Achmad A1 - Neher, Dieter A1 - Lieberwirth, Ingo A1 - Wegner, Gerhard A1 - Allard, Sybille A1 - Scherf, Ullrich T1 - Unexpectedly high field-effect mobility of a soluble, low molecular weight oligoquaterthiophene fraction with low polydispersity N2 - Layers made from soluble low molecular weight polythiophene PQT-12 with low polydispersity exhibit a highly ordered structure and charge-carrier mobilities of the order of 10(-3) cm(2)/(V s), which we attribute to its proximity to monodispersity. We propose that polydispersity is a decisive factor with regard to structure formation and transport properties of soluble low molecular weight polythiophenes.
