Water-scavenging agent for an organic electroluminescent device and organic electroluminescent device comprising same

摘要

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: 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 M is a metal having a coordination number of 6.
