NEW POLYALKOXYQUINQUEPHENYL DERIVATIVE, HOST MATERIAL COMPRISING THE SAME AND ORGANIC ELECTROLUMINESCENT ELEMENT USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a new polyalkoxyquinquephenyl derivative that enables low-voltage driving of an element and provides a high-efficiency element, a host material comprising the same and an organic electroluminescent element using the same. SOLUTION: The polyalkoxyquinquephenyl derivative is represented by a representative compound 4-MeOPTB as shown by the formula. The host material comprises the same. The organic electroluminescent element uses same. COPYRIGHT: (C)2010,JPO&INPIT
