Abstract

PURPOSE:To obtain the oligomer, having a specified structure and useful for a stimulation-responsive material having a highly functional surface due to its ability to fix to a carrier having silanol groups such as glass through a covalent bond while holding the responsiveness to pH and temperatures. CONSTITUTION:This oligomer has a structure expressed by the formula [R<1>, R<3> and R<4> are each a 1-4C alkyl; R<2> and R<5> are each a 1-4C alkyl chain; (n) is 1-100]. The oligomer is obtained by carrying out the anionic polyaddition reaction of a dialkyldivinylsilane, e.g., dimethylvinylsilane with an N,N'- dialkylethylenediamine, e.g., N,N'-diethylethylene diamine and then add a thiol containing siloxy such as 3-mercaptopropyltrimethoxysilane to the vinyl terminal of the resultant oligomer in the presence of a radical former such as azobisisobutyronitrile.

It is recognized that this oligomer is water-soluble and has a responsiveness to pH and temperature as an aqueous solution property. Regarding the pH responsiveness, after the amino group of the oligomer is protonated with hydrochloric acid and dissolved in water,
Titration with an aqueous solution of sodium hydroxide to examine the change in light transmittance (turbidity) of the aqueous solution revealed that at any temperature,
It has been found that the transmittance changes significantly in response to slight pH changes. This is because a slight change in pH causes a rapid change in the solubility of the oligomer and a change in the turbidity. Also, with respect to temperature changes,
It has a sharp responsiveness because the solubility of the oligomer changes abruptly.

Polysylamine oligomers have many possible applications as materials for modifying various material surfaces to prepare highly functional surfaces. In order to exert its properties effectively, it is better to fix one end to the surface by covalent bonding rather than simply coating the surface. This is because the mere coating cannot sufficiently exhibit the responsiveness to various stimuli because some oligomers are washed away by washing the surface or the presence state of the oligomer on the surface is not always constant. However, since the polysylamine oligomer does not have a reactive group for covalent bonding, there is a problem in that it cannot be covalently immobilized on a carrier containing silicon such as glass or silica gel which is often used as a functional material.

As a result of earnest research, the present inventors have found that in order to immobilize an oligomer on the surface of a carrier containing silicon such as glass or silica gel by a covalent bond, silanol existing on the surface of the carrier is used. It has been found that it is preferable to use a group. Then, it was found that a polysylamine oligomer having a diamine skeleton and a silyl group in the main chain and a siloxy group at the terminal can be immobilized on the surface of the carrier by a covalent bond while maintaining the responsiveness to pH and temperature. The present invention has been completed based on these findings.

Since it has a siloxy group capable of reacting with a silanol group at the terminal, it can be covalently immobilized on a carrier having a silanol group such as glass. Since the responsiveness to pH and temperature is maintained even when the oligomer is immobilized, it can be immobilized on the glass plate surface to prepare a cell culture bed that enables specific cell adhesion. Also,
It can be fixed on the surface of a glass electrode or the like to prepare a sensor that responds to pH change or temperature change, or fixed on the surface of a silica gel-supported catalyst and used to control the catalyst activity according to the reaction temperature change. . Further, the sulfate ion has a large binding constant because it has a stable structure between the silicon atom and the two nitrogen atoms present on both sides thereof, and can be used for ion separation. As described above, by using the polysylamine oligomer of the present invention, it becomes possible to prepare a stimuli-responsive material having a highly functional surface.
