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 above with a diamine or dicarboxylic acid monomer represented by Formula 2 above, 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 or diamine monomer represented by Formula 1 below and a diamine or dicarboxylic acid monomer represented by Formula 2 below in a solvent to prepare a solution including the diacetylene-containing dicarboxylic acid or diamine monomer and a solution including the diamine or dicarboxylic acid monomer:
G-(A) x -C≡C—C≡C—(B) y -G  [Formula 1]

wherein A and B are each independently selected from 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 selected from COOH and NH 2 , 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 a substituted or unsubstituted alkyl group of one or more carbon atoms, a benzene group, a cycloalkyl group, a pyridine group, a pyrimidine group and a naphthalene group, D and E are each independently selected from a substituted or unsubstituted alkyl group of one or more carbon atoms, a benzene group, a cycloalkyl group, a pyridine group, a pyrimidine group and a naphthalene group, D, E and Z are different from each other, Q is selected from COOH and NH 2 , m and n are each independently an integer of 0 to 20, and G of Formula 1 above is different from Q of Formula 2 above; (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 or diamine monomer represented by Formula 1 above with the solution including the diamine or dicarboxylic acid monomer represented by Formula 2 above to form a radial porous diacetylene particle and then growing the radial porous diacetylene 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 or diamine monomer represented by Formula 1 above and the solution including the diamine or dicarboxylic acid 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 or diamine monomer represented by Formula 1 above and the solution including the diamine or dicarboxylic acid monomer represented by Formula 2 above has a concentration of 10 mM˜20 mM.

5 . The method according to claim 1 , wherein the solution including the diacetylene-containing dicarboxylic acid or diamine monomer represented by Formula 1 above and the solution including the diamine or dicarboxylic acid monomer represented by Formula 2 above are maintained at a room temperature of 5˜30° C. for 10 minutes˜1 hour during a mixing process.

6 . The method according to claim 1 , wherein the solution including the diacetylene-containing dicarboxylic acid or diamine monomer represented by Formula 1 above and the solution including the diamine or dicarboxylic acid monomer represented by Formula 2 above are maintained at a room temperature of 10˜25° C. for 10 minutes˜1 hour during the process of mixing the solution.

7 . The method according to claim 1 , wherein the solution including the diacetylene-containing dicarboxylic acid or diamine monomer represented by Formula 1 above and the solution including the diamine or dicarboxylic acid 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.
