High Charge Carrier Mobility in Porphyrin Nanoribbons
Polydisperse edge-fused nickel(II) porphyrin nanoribbons have been synthesized by Yamamoto coupling followed by gold(III)-mediated fusion, with average degrees of polymerization of up to 37 repeat units (length 31 nm). Time-resolved optical-pump terahertz spectroscopy measurements indicate that photo-generated charge carriers have dc mobilities of up to 205 cm<sup>2</sup> V<sup>-1</sup> s<sup>-1</sup> in these nanoribbons, exceeding the values previously reported for most other types of nanoribbon or π-conjugated polymer.
