Optically transparent mesoporous polymers based on anionic macroinitiators and 2,4-toluene diisocyanate

Optically transparent mesoporous polymers have been synthesized through the anionic polymerization of 2,4-toluene diisocyanate initiated by anionic macroinitiators. The influence of the molecular weight of the macroinitiators on the formation behavior of amphiphilic block copolymers has been considered along with the role of substituted urea in the stabilization of the O-polyisocyanate blocks. The features of the supramolecular organization of mesoporous polymers have been studied. It has been shown that an increase in the proportion of O-polyisocyanate blocks in the coplanar trans configuration in the polymers is accompanied by a significant decrease in their volume electrical resistivity values. The preferential formation of amphiphilic block copolymers is reflected in the formation of highly ordered domains and perfection of the supramolecular cellular geometry of mesoporous polymers. It has been found that the mesoporous polymer structuring enables the immobilization of organic chromophores. It has been shown that luminophores in the cavities of mesopores generate laser radiation and exhibit high resistance to high-power laser radiation.
