Synthesis of fluorescent porous polyurea network by organic sol-gel polymerization |
| 초록 |
Fluorescent polyurea network was synthesized by polymerization of tetrakis(4-aminophenyl) porphyrin (TAPP) and hexametylene diisocyanate (HDI). Polymerization of TAPP and HDI was confirmed by UV-vis and fluorescence spectra. The urea network polymer shows sol-gel transition above critical gelation time or concentration. The morphology and porosity of the resultant organic molecular networks were studied by scanning electron microscope(SEM) and gas adsorption measurement. We also performed the sol-gel copolymerization of two mixed amine monomers, TAPP and tetrakis(4-aminophenyl) methane (TAPM) with HDI. Optical property of the copolyurea network was varied by changing molar ratio of the amines. |
