Hydrogen-bonding pyrazolyl and imidazolyl motifs are incorporated into organoplatinum(II) complexes and found to be harmonized with extended π-π and Pt II Pt II 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 cm 2 V −1 s −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.
