Abstract

There is provided a novel organic silicon compound that can be used for a silane coupling agent. An organic silicon compound of Formula (1):

(where A − is Formula (2) or Formula (3):

E is Formula (4) or Formula (5):

R 1 and R 2 are each independently a C 1-5 alkyl group, R 3 is a hydrogen atom or a methyl group, R 4 and R 5 are each independently a C 1-5 alkyl group, m, n, and p are each independently an integer of 1 to 5, and q is an integer of 1 to 3).

First claim

The invention claimed is:

1. An organic silicon compound of Formula (1):

where A − is Formula (2) or Formula (3):

E is Formula (4) or Formula (5):

a carbonyl group in each of Formula (4) and Formula (5) is bonded to a carbon atom to which R 3 is bonded, R 1 and R 2 are each independently a C 1-5 alkyl group, R 3 is a hydrogen atom or a methyl group, R 4 and R 5 are each independently a C 1-5 alkyl group, m, n, and p are each independently an integer of 1 to 5, and q is an integer of 1 to 3.

2. A silane coupling agent comprising:
the organic silicon compound as claimed in claim 1 ;
a polar organic solvent; and
water.

3. The silane coupling agent according to claim 2 , further comprising an organic acid.

4. An adherence inhibitor for a biological substance or a cell, comprising the silane coupling agent as claimed in claim 2 .

5. The adherence inhibitor according to claim 4 , wherein
the cell is a platelet.

6. A method for immobilizing a silane coupling agent, the method comprising the steps of:
applying the silane coupling agent according to claim 2 onto a substrate and baking the silane coupling agent;
washing the substrate with a polar solvent; and
drying the substrate.

7. A method for immobilizing a silane coupling agent, the method comprising the steps of:
immersing a substrate in the silane coupling agent according to claim 2 ;
washing the substrate with a polar solvent; and
drying the substrate.

8. An adherence inhibitor for a biological substance or a cell, comprising the silane coupling agent as claimed in claim 3 .

9. The adherence inhibitor according to claim 8 , wherein
the cell is a platelet.

10. A method for immobilizing a silane coupling agent, the method comprising the steps of:
applying the silane coupling agent according to claim 3 onto a substrate and baking the silane coupling agent;
washing the substrate with a polar solvent; and
drying the substrate.

11. A method for immobilizing a silane coupling agent, the method comprising the steps of:
immersing a substrate in the silane coupling agent according to claim 3 ;
washing the substrate with a polar solvent; and
drying the substrate.
