Scientists Develop Light Emitting Metallacages and Metallacycles

A group of researchers have recently developed platinum-organic metallacages and metallacycles which are light emitting in nature. Peter J Stang, a professor at the University of Utah talked in much detail about the complexes of supramolecular coordination which are self assembling. By choosing combinations of organic linking groups and angular and linear metal complexes, several researchers have been able to create 2 and 3 dimensional molecules having brilliant geometries and the property of versatility. 

The molecules are being explored and examined by the researchers as chemical sensors that are optoelectronic. And these are like building blocks that are meant for fibers and hydrogels, and also like bioprobes that are for monitoring and visualizing physiological processes. Another team of researchers led by J. Bryant Pollock, brought together bis(ethynylpyridine)aniline ligands along with phenanthrene complex which is platinum based in order to create rings that are in the shape of rhombus. 

The light emitted by the molecules when they are fluoresce can easily be altered to span throughout the spectrum that is visible. This can be done by changing the constituents present on the specific aniline ring. The research team also demonstrated that tumor cells have the capacity to slurp the rhomboidal metallacycles and can exhibit anticancer activity. Molecules can also be created for image-based drug delivery. 

Moreover, Stang’ s research team also worked in close collaboration with China based research group wherein the groups combined the complex of platinum phosphine, a certain benzene dicarboxylate, and also a pyridyl based tetraphenylethylene for developing metallacages which could further get decorated with different types of functional groups like house molecules and external sugars.
