## CPC

- C07F 5/066: {compounds with Al linked to an element other than Al, C, H or halogen (this includes Al-cyanide linkage)}
- C07F: ACYCLIC, CARBOCYCLIC OR HETEROCYCLIC COMPOUNDS CONTAINING ELEMENTS OTHER THAN CARBON, HYDROGEN, HALOGEN, OXYGEN, NITROGEN, SULFUR, SELENIUM OR TELLURIUM (metal-containing porphyrins C07D487/22)

## Abstract

By reacting trialkyl aluminum (AlR3) with 2-position substituted 8-quinolinol (q′H) at a mole ratio of 1:2, an AlRq′2-type aluminum compound having a specified structural formula is manufactured. The resulting compound is further reacted with an active hydrogen-containing organic compound to obtain a derivative such as an Alq′2q type derivative (wherein q represents 8-quinolinolato ligand and q′ represents 2-position substituted 8-quinolinolato ligand).

## Claims

### Claim 1

An AlRq′2-type aluminum compound shown by the following general formula (I):
5
wherein R represents an alkyl group with a carbon number of not more than 6, R1 and R2 respectively represent an alkyl group, alkoxy group, or dialkylamine group (NR′R″: wherein R′ and R″ respectively represent an alkyl group having a carbon number of not more than 3.) having a carbon number of not more than 6.

### Claim 2 (depends on 1)

A method for manufacturing an AlRq′2-type aluminum compound according to claim 1, which comprises reacting trialkyl aluminum (AlR3) with 2-position substituted 8-quinolinol (q′H) at a mole ratio of 1:2.

### Claim 3 (depends on 1)

A derivative derived from an AlRq′2-type aluminum compound produced by reacting an AlRq′2-type aluminum compound according to claim 1 with an active hydrogen-containing organic compound.

### Claim 4 (depends on 3)

A derivative according to claim 3, wherein the active hydrogen-containing organic compound is at least one selected from the group consisting of 8-quinolinole, phenol, aniline, thiol and a derivative thereof.

### Claim 5 (depends on 3)

A derivative according to claim 3, wherein the derivative is an Alq′2q-type aluminum compound and q is 8-quinolinol.

### Claim 6

A polymer having a repeating unit shown by the following general formula (II) or (III):
6
wherein R3 and R4 respectively represent a normal chain or branched chain alkyl group having a carbon number of not more than 20, and n represents an integer of 2 to 50.

### Claim 7 (depends on 3, 6)

A derivative according to claim 3, wherein the active hydrogen-containing organic compound is a polymer according to claim 6.
