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.
