Magnus' Green Salt Revisited: Impact of Platinum-Platinum Interactions on Electronic Structure and Carrier Mobilities

摘要

The quest for semiconducting materials that could combine high charge-carrier mobilities and ease of processability has recently triggered renewed interest in a class of hybrid organic-inorganic materials that had been extensively studied several decades ago. Tailoring the alkyl side groups of the otherwise insoluble Magnus' green salt (MGS), [PtCl_4][Pt(NH_2R)_4] (R = side group; in MGS itself, R = H), allows the synthesis of solution-processable, environmentally stable MGS derivatives with intrinsic hole mobilities reaching 0.06 cm~2 V~(-1) s~(-1)in polycrystalline films.
