Claim:
An aluminum complex represented by the general formula (1′) below: [Al 2 (L 1 ) n (L 2 ) 3-n ] m (1′) wherein in the formula (1′), n represents an integer of 1 or 2; m represents a natural number; L 1 represents a ligand represented by the formula (2′) below; L 2 represents a ligand represented by the formula (3-A′) below or the formula (3-B′) below, with the proviso that when n=2, the ligand represented by the formula (2′) below is an optically active substance and when n=1, the ligand represented by the formula (3-A′) below or the formula (3-B′) below is an optically active substance, in the formula (2′), R 1 , R 2 , R 3 , R 4 , R 1′ , R 2′ , R 3′ , and R 4′ each independently represent a hydrogen atom, a halogen atom, a hydroxy group, a saturated or unsaturated carbon chain, an aryl group that may have a substituent, a heterocyclic group that may have a substituent, an alkoxy group, an aryloxy group, an aralkyloxy group, a carboxy group that may be protected with a protecting group, an amino group, a substituted amino group, a nitro group, an acyl group, a substituted silyl group, a thio group, a mercapto group, or a polymer chain, and R 1 and R 2 , R 2 and R 3 , R 3 and R 4 , R 4 and R 4′ , R 4′ and R 3′ , R 3′ and R 2′ , and R 2′ and R 1′ may be taken together to form a ring; in the formula (3-A′), R 5 , R 6 , R 7 , and R 8 each independently represent an aryl group that may have a substituent, a heterocyclic group that may have a substituent, an aliphatic chain that may have a substituent or an alicyclic group that may have a substituent, and ring A represents a 3- to 8-membered ring that may have a hetero element, and R 5 and R 6 , and R 7 and R 8 may be taken together to form a ring; and in the formula (3-B′), R 5 , R 6 , R 7 and R 8 have the same meanings as defined above, Y 1 and Y 2 each independently represent an aliphatic chain that may have a substituent, an alicyclic group that may have a substituent, an aryl group that may have a substituent, a heterocyclic group that may have a substituent, an alkoxy group, a siloxy group that may have a substituent or a carboxy group, and R 5 and R 6 , and R 7 and R 8 may be taken together to form a ring.
