High mobility at the interface of the cocrystallized sandwich-type tetrapyrrole metal compound and fullerene layers†
Abstract
Organic field effect transistor (OFET) devices fabricated based on triple-decker mixed-(phthalocyaninato)(porphyrinato) yttrium(III) and fullerene cocrystals show high carrier mobilities of 3.72 and 2.22 cm2 V−1 s−1 for holes and electrons, respectively, at the interface of cocrystallized supramolecular layers, representing one of the most excellent cocrystal ambipolar OFET devices reported thus far.
