Yam* Department of Chemistry, The University of Hong Kong, Pokfulam Road, Hong Kong, PR China wwyam@hku.hk; chanmym@hku.hk A novel class of luminescent cyclometalated platinum(II) 1,3-bis-(N-alkylbenzimidazol-2c-yl)benzene (bzimb) complexes has been designed and synthesized.13 The emission color can be readily tuned by the introduction of various substituents to the anionic phenyl rings of the bzimb ligand.2,3 Their photophysical, electrochemical and electroluminescence properties have been investigated. Efficient organic light-emitting devices (OLEDs) have been fabricated based on this class of complexes using vacuum deposition and solution-processing techniques.2,3  To further improve the solution-processable device performance, dendritic pendants have been successfully incorporated into the platinum(II) complexes. The dendritic platinum(II) complexes show remarkable photoluminescence quantum yields of up to 80 % in spin-coated thin films. The solution-processable OLEDs show remarkable performances with high EQEs, suggesting a promising class of dendritic platinum(II) complexes for solution-processable OLEDs.     1 A. Y.-Y. Tam, D.
