摘要：

Organization of phosphorescent domains in seld-assembled block copolymers is demonstrated to yield dual emission for white electroluminescence. Our block-copolymer approach minimizes energy transfer between two colored species by site isolation through morphology control, allowing higher loading concentration of red emitters with improved device performance.
