Abstract
A water-capturing or drying agent placed in a hermetically sealed field light emission device for maintaining stable light emission of the light emission device not susceptible to moisture and oxygen for long period of time. The drying agent comprises a compound of polymer formed by bonding M constituting a plurality of organometallic compounds wherein M is a trivalent metal atom with an oxygen molecule. The drying agent is placed in the hermetically sealed container, thereby protecting the field light emission device from being adversely affected by damage from trace amounts of moisture permeating from outside the hermetically sealed container and/or adhered to the inner surface thereof.
Claims20
A drying agent comprising a compound of a polymer formed by bonding a metallic atom of an organometallic compound having a multiple-membered structure with an oxygen molecule.
A drying agent comprising a polymer formed by bonding a plurality of compounds shown by chemical formula (1) with an oxygen atom;
- [Wherein, R1, R2, and R3 are a hydrogen atom or an alkyl group, aryl group, cycloalkyl group, or heterocyclic ring group having one or more carbon atoms. One or more hydrogen atoms in each of groups may be substituted for a halogen atom. R1, R2, and R3 may be from different groups, may be from the same group, may be bonded to each other, or may be a polymer. M is a trivalent metal atom.].
A drying agent comprising a compound illustrated by chemical formula (2);
- [Wherein, R is a hydrogen atom or an alkyl group, aryl group, cycloalkyl group, heterocyclic ring group having one or more carbon atoms. One or more hydrogen atoms in each of groups may be substituted for a halogen atom. R may be from different groups, may be from the same group, may be bonded to each other, or may be a polymer, and n is 0 or an integer of 1 and above. M is a trivalent metal atom.].
A drying agent comprising a compound illustrated by chemical formula (3);
- [Wherein, R is a hydrogen atom or an alkyl group, aryl group, cycloalkyl group, heterocyclic ring group having one or more carbon atoms. One or more hydrogen atoms in each of groups may be substituted for a halogen atom. R may be from different groups, may be from the same group, may be bonded to each other, or may be a polymer, and n is 0 or an integer of 1 and above. M is a trivalent metal atom.].
A drying agent comprising a compound illustrated by chemical formula (4);
- [Wherein, R is a hydrogen atom or an alkyl group, aryl group, cycloalkyl group, heterocyclic ring group having one or more carbon atoms. One or more hydrogen atoms in each of groups may be substituted for a halogen atom. R may be from different groups, may be from the same group, may be bonded to each other or may be a polymer, and m1, m2 and m3 are an integer of 1 and above and may be different each other or same each other. M is a trivalent metal atom.].
