A novel water-scavenging agent of the present invention comprising a compound
of
formula (I) as a primary component can be dissolved in a polar solvent and coated
by a screen printing method, and the inventive organic EL device comprising same
can maintain stable luminescent characteristics for a prolonged time:
##STR1##
wherein,
R1, R2, R3, R4, R5
and R6 are each independently hydrogen; halogen; alkyl, aryl, cycloalkyl
or hetero-ring, optionally substituted with at least one halogen atom, and
