摘要：

Efficient blue and white single-doped organic light-emitting devices based a novel platinum complex - platinum(II) [1,3-difluoro-4,6-di(2-pyridinyl) benzene] chloride - are reported (see figure). The blue and white devices show peak efficiencies of 16% and 9% and CIE chromaticity coordinates of (0.15, 0.26) and (0.33, 0.36), respectively. These results demonstrate that the utilization of platinum complexes is a viable approach for the development of blue electrophosphorescent devices.
