Self-assembly of a neutral platinum(II) complex into highly emitting microcrystalline fibers through metallophilic interactions

The solvent-assisted self-assembly of a blue-emitting neutral platinum(II) complex into micrometer-long and highly crystalline fibers has been achieved. The aggregates show highly efficient (quantum yield up to 74%) polarized yellow-orange light emission, as a consequence of their high degree of supramolecular order imparted by weak non-covalent intermolecular (metal...metal and pi-pi) interactions.
