Abstract

Provided are a radial porous diacetylene particle, which is synthesized by ion-bonding a diacetylene-containing dicarboxylic acid or diamine monomer represented by Formula 1 with a diamine or dicarboxylic acid monomer represented by Formula 2, and a method of manufacturing the same.

First claim

What is claimed is:

1. A method of manufacturing a radial porous diacetylene particle, comprising the steps of:
(a) respectively dissolving a diacetylene-containing dicarboxylic acid monomer represented by Formula 1 below and a diamine monomer represented by Formula 2 below in a solvent to prepare a solution including the diacetylene-containing dicarboxylic acid monomer and a solution including the diamine monomer:
G-(A) x -C≡C—C≡C—(B) y -G  [Formula 1]

wherein A and B are each independently selected from the group consisting of a substituted or unsubstituted alkyl group of two or more carbon atoms, an ethylene oxide group, an amide group and an ester group, G is COOH, and x and y are each independently an integer of 1 to 20,
Q-(D) m -Z-(E) n -Q  [Formula 2]

wherein Z is selected from the group consisting of a benzene group, a pyridine group, a pyrimidine group and a naphthalene group, D and E are each independently a substituted or unsubstituted alkyl group of one or more carbon atoms Q, NH 2 , and m and n are each independently an integer of 0 to 20;
(b) ultrasonically treating each of the solutions;
(c) maintaining each of the ultrasonically-treated solutions at room temperature; and
(d) mixing the solution including the diacetylene-containing dicarboxylic acid monomer represented by Formula 1 above with the solution including the diamine monomer represented by Formula 2 above to form a radial porous diacetylene particle and then growing the radial porous acetylene particle.

2. The method according to claim 1 , wherein the solvent is at least one selected from the group consisting of tetrahydrofuran (THF), chloroform, toluene, ethanol, isopropanol, and n-hexane.

3. The method according to claim 1 , wherein each of the solution including the diacetylene-containing dicarboxylic acid monomer represented by Formula 1 above and the solution including the diamine monomer represented by Formula 2 above has a concentration of 10 mM˜50 mM.

4. The method according to claim 1 , wherein each of the solution including the diacetylene-containing dicarboxylic acid monomer represented by Formula 1 above and the solution including the diamine monomer represented by Formula 2 above has a concentration of 10 mM˜20 mM.

5. The method according to claim 1 , wherein a mixing temperature of the step (d) is maintained at a temperature of 5˜30° C. for 10 minutes˜1 hour.

6. The method according to claim 1 , wherein a mixing temperature of the step (d) is maintained at a temperature of 10˜25° C. for 10 minutes˜1 hour.

7. The method according to claim 1 , wherein the solution including the diacetylene-containing dicarboxylic acid monomer represented by Formula 1 above and the solution including the diamine monomer represented by Formula 2 above are mixed in a volume ratio of 1:0.2˜5.

8. The method according to claim 1 , wherein the ultrasonic treatment is carried out for 30 minutes by a power of 5˜20 W.
