Abstract

A compound represented by formula (1) is provided:

wherein M represents an aluminum atom, a titanium atom, a silicon atom, or a boron atom; m represents 1 or 2; n represents a positive integer; R 1 , R 2 and R 3 each independently represent a C1-16 alkyl group optionally substituted with one or more fluorine atoms or a C2-17 acyl group optionally substituted with one or more fluorine atoms; and in the case where a plurality of R 3 is present, the plurality of R 3 may be the same or different to each other.

First claim

What is claimed is:

1. A compound represented by formula (1):

wherein M represents an aluminum atom, a titanium atom, a silicon atom, or a boron atom; m represents 1 or 2; n represents a positive integer; R 1 , R 2 and R 3 each independently represent a C1-16 alkyl group optionally substituted with one or more fluorine atoms, or a C2-17 acyl group optionally substituted with one or more fluorine atoms, and in the case where a plurality of R 3 is present, the plurality of R 3 may be the same or different to each other;
a part of the carbon atoms composing the C1-16 alkyl group optionally substituted with one or more fluorine atoms may be replaced with one or more oxygen atoms, and a part of the carbon atoms composing the C2-17 acyl group optionally substituted with one or more fluorine atoms may be replaced with one or more oxygen atoms; and
a proportion of a total number of the fluorine atoms in R 1 , R 2 and R 3 is 15% or more relative to a total number of the fluorine atoms and hydrogen atoms in R 1 , R 2 and R 3 , and in the case where at least one of R 1 , R 2 and R 3 is an acyl group substituted with one or more fluorine atoms, at least another one of R 1 , R 2 and R 3 is an alkyl group substituted with one or more fluorine atoms.

2. The compound according to claim 1 , wherein M is an aluminum atom.

3. The compound according to claim 1 , wherein R 1 , R 2 and R 3 are a C2-8 alkyl group substituted with one or more fluorine atoms.

4. A drying agent comprising the compound according to claim 1 .

5. The drying agent according to claim 4 , further comprising a viscosity modifier.

6. A sealing structure, wherein a pair of substrates is sealed with a sealing agent, and
the sealing structure comprises the drying agent according to claim 4 therein.

7. An organic EL element comprising:
an element substrate;
a sealing substrate disposed opposite to the element substrate;
a laminate being provided on the element substrate and including an organic layer interposed between a pair of electrodes; and
a sealing agent sealing outer peripheral parts of the element substrate and the sealing substrate;
wherein a sealed space is filled with the drying agent according to claim 4 .
