Abstract
An organic EL device is disclosed in which is placed a transparent water-capturing film comprising an easy-to-use organometallic compound illustrated by the chemical formula (1): wherein, R1, R2 and R3 are selected from the group consisting of alkyl group, aryl group, cycloalkyl group, heterocyclic group and acyl group having one carbon atom and above, and M is a trivalent metallic atom.
Claims22
A method for absorbing moisture from an environment, the method comprising:
- placing in the environment a drying agent comprising an organometallic compound illustrated by the formula (1);
- wherein, R1, R2 and R3 are selected from the group consisting of alkyl group, aryl group, cycloalkyl group, heterocyclic group and acyl group having at least one carbon atom, and M is a trivalent metallic atom, whereby moisture is absorbed from the environment.
A method for absorbing moisture from an environment, the method comprising:
- placing in the environment a drying agent comprising an organometallic compound illustrated by the formula (2);
- wherein, R1, R2, R3, R4 and R5 are selected from the group consisting of alkyl group, aryl group, cycloalkyl group, heterocyclic group and acyl group having at least one carbon atom, and M is a trivalent metallic atom, whereby moisture is absorbed from the environment.
A method for absorbing moisture from an environment, the method comprising:
- placing in the environment a drying agent comprising an organometallic compound illustrated by the formula (3);
- wherein, R1, R2, R3 and R4 are selected from the group consisting of alkyl group, aryl group, cycloalkyl group, heterocyclic group and acyl group having at least one carbon atom, and M is a quadrivalent metallic atom, whereby moisture is absorbed from the environment.
