Disclosed is an electrolyte for a secondary battery, comprising an eutectic mixture consisting of: (a) am amide group-containing compound with at least one EDG introduced into the N-position thereof; and (b) an ionizable lithium salt. Also, provided are a secondary battery comprising such an electrolyte, and a method of adjusting an electrochemical stability window of an eutectic mixture consisting of an amide group-containing compound and a lithium salt by regulating electron donating properties of at least one substituent group introduced into the N-position of the amide group-containing compound.

Novel materials for electron injection/transportation and emitting layers can greatly improve the stability of an organic electroluminescent display. Electroluminescent displays incorporating these materials produce blue light at low voltage levels. These novel organic materials include compounds in which 1 to 2 imidazole functional groups are introduced in the 2 or 2,6-site of 9,10 substituted anthracene. An organic electroluminescent display with an organic compound layer of these materials has high efficiency, thermal stability, operationally stability and maintains driving voltage before and after operation.
