Pyridylenevinylene based Cu(2+)-specific, injectable metallo(hydro)gel: thixotropy and nanoscale metal-organic particles.

A Cu(2+)-selective metallo(hydro)gelation of a p-pyridyl ended oligo-phenylenevinylene system is reported over its respective meta- and ortho-regioisomers. The metallogel formed via the self-assembly of the nanoscale-metal-organic particles is injectable and also shows multi-stimuli responsiveness, including thixotropy.
