Surface modified polymer hollow nanocapsules, and method for preparing the same

The present invention relates to surface-modified polymer hollow nanocapsules in which polymer hollow nanocapsules, formed via polymerization of a composition containing a compound represented by chemical formula 1, are surface-modified to have a positive zeta potential when dispersed in water; and a method of preparing the same. In the chemical formula 1: X is subphthalocyanine, phthalocyanine, or porphyrin; L_1 is -OR_1- or -SR_2-, wherein the R_1 and R_2 are each independently a direct bond, an alkylene group having 1-10 carbon atoms, an alkenylene group having 2-10 carbon atoms, a cycloalkylene group having 6-20 carbon atoms, a cycloalkenylene group having 6-20 carbon atoms, or an arylene group having 6-20 carbon atoms; Y_1 is a vinyl group, an acryl group, a methacryl group, a thiol group, or an amine group; and m is an integer of 3-10.COPYRIGHT KIPO 2018

A facile reprecipitation method for the preparation of polyimide hollow spheres with controllable morphologies and permeable shell

We present our preliminary work on the fabrication of polyimide hollow sphere by reprecipitation. Through fine-tuning the PAA concentration, many intriguing shapes, including deflated capsules, bowl-shaped and dimple-like hollow spheres can be obtained. Adding salt to the PAA solution helps the formation of PI hollow spheres with complete shells. The morphologies can be fixed through imidization, thus obtaining a controllable and reproducible method to prepare high-performance polyimide hollow spheres with various morphologies.

A simple synthesis of 4,5-disubstituted 1,2-dicyanobenzenes and 2,3,9,10,16,17,23,24-octasubstituted phthalocyanines

4,5-Dichloro-1,2-dicyanobenzene (5) was prepared in an overall yield of 49% from 4,5-dichloro-1,2-benzenedicarboxylic acid (1). The reactions of 5 with phenols, thiophenol and 1-propanethiol led in a nucleophilic displacement reaction to the 4,5-bis(aryloxy)-, 4,5-bis(phenylthio)- and 4,5-bis(propylthio)-1,2-dicyanobenzenes 6 which were converted in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene in high yields to octasubstituted phthalocyanines (tetrabenzoporphyrazines) 7. Some compounds 7 contain eight free phenolic, carboxylic acid or pyridyl groups.
