Abstract

original image

Organometallic nanowires with luminescent and current-modulating properties were self-assembled from cyclometalated/terpyridyl platinum(II) complexes with auxiliary arylisocyanide/arylacetylide ligands and incorporated into a compact organic light-emitting field-effect transistor (see picture) by solution-processable protocols. The nanowires exhibit both electron and hole mobilities of 0.1 cm2 V−1 s−1.
