A new norbornene dicarboximide presenting a pendant carbazole moiety linked by a p-methylene benzyl spacer is synthesized. This carbazole-functionalized monomer is polymerized via ring-opening metathesis polymerization using Grubbs third-generation catalyst. Microstructural anal. of resulting polymers performed by NMR shows that they are stereoirregular. Wide-angle X-ray diffraction (WAXD) and thermal (DSC) anal. indicate that polymers are also amorphous. With respect to the fluorescence anal., both solution and film polymer samples exhibit only “”normal structured”” carbazole fluorescence, while excimer formation by overlap of carbazole groups is not detected. In the experiment, the researchers used many compounds, for example, 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Recommanded Product: 623-24-5)
1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Most of the natural organobromine compounds are produced by marine organisms , and several brominated metabolites with antibacterial , antitumor , antiviral , and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. Moreover, several studies demonstrate that the average proportion of bromine in drugs is significantly higher than that in natural products. Recommanded Product: 623-24-5
