New Findings from Technical University Describe Advances in General Science (Halogen-bonded mesogens direct polymer self-assemblies up to millimetre length scale)

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Science are presented in a new report. According to news reporting originating in Milan, Italy, by NewsRx journalists, research stated, "Aligning polymeric nanostructures up to macroscale in facile ways remains a challenge in materials science and technology. Here we show polymeric self-assemblies where nanoscale organization guides the macroscopic alignment up to millimetre scale."

The news reporters obtained a quote from the research from Technical University, "The concept is shown by halogen bonding mesogenic 1-iodoperfluoroalkanes to a star-shaped ethyleneglycol-based polymer, having chloride end-groups. The mesogens segregate and stack parallel into aligned domains. This leads to layers at similar to 10 nm periodicity. Combination of directionality of halogen bonding, mesogen parallel stacking and minimization of interfacial curvature translates into an overall alignment in bulk and films up to millimetre scale. Upon heating, novel supramolecular halogen-bonded polymeric liquid crystallinity is also shown."

According to the news reporters, the research concluded: "As many polymers present sites capable of receiving halogen bonding, we suggest generic potential of this strategy for aligning polymer self-assemblies."
