Single microcrystals of organoplatinum(II) complexes with high charge-carrier mobility
Authors
Abstract
Hydrogen-bonding pyrazolyl and imidazolyl motifs are incorporated into organoplatinum(II) complexes and found to be harmonized with extended π–π and PtII⋯PtII interactions to align the planar cations into a quasi-1-D columnar structure or a quasi-2D framework. A field-effect electron mobility up to 20 cm2V−1s−1 has been recorded with a single-microcrystal transistor. In addition, crystalline samples of one of the organoplatinum(II) complexes show intriguing thermoluminescent and vapoluminescent properties.
