ELECTROLUMINESCENT DEVICE COMPRISING AN ELECTROLUMINESCENT MATERIAL OF AT LEAST TWO METAL CHELATES

摘要

The invention pertains to an electroluminescent device comprising an electroluminescent material of at least two metal chelates, each metal chelate comprising a metal and chelating moieties, which metal chelates are connected to each other through a &pgr;-conjugated spacer or through a &sgr;-conjugated spacer with enhanced through bond interaction. The electroluminescent material is used in LEDs and LECs.
