AI Article Synopsis
- Conventional platinum complexes usually create one-dimensional structures due to specific interactions, but cruciform-shaped organoplatinum(II) complexes can develop two-dimensional microcrystals.
- These 2D microcrystals exhibit full-color and white phosphorescence and highlight unique stacking interactions between different ligands.
- The research shows that these organoplatinum(II) complexes can be effectively used to create advanced phosphorescent materials for photonic applications.
Article Abstract
Conventional square-planar platinum complexes typically form one-dimensional assemblies as a result of unidirectional metallophilic and/or π⋅⋅⋅π intermolecular interactions. Organoplatinum(II) complexes with a cruciform shape are presented herein to construct two-dimensional (2D) microcrystals with full-color and white phosphorescence. These 2D crystals show unique monocomponent π⋅⋅⋅π stacking, from either the cyclometalating or noncyclometalating ligand, and the bicomponent alternate π⋅⋅⋅π stacking from both ligands along different facet directions. Anisotropic tri-directional waveguiding is further implemented on a single hexagonal microcrystal. These results demonstrate the great capability of the organoplatinum(II) cruciform as a general platform to fabricate 2D phosphorescent micro-/nanocrystals for advanced photonic applications.
