Amphiphilic blockcopolymers autoassemble in water to form either dynamically active micelles or frozen particles at high surface tension. The dynamics of these systems is dominated by an individual process, which involves insertion–expulsion of copolymer chains, and a collective one, which involves fusion and fragmentation of proper micelles. The details of these mechanisms can drastically affect
binary functionalized lowmolecular weight organicgelators (FLMOGs) and gels thereof in selected organic solvents were synthesized and characterized. The functionality refers to a functional group that does not take part in formation of the supramolecular gel network, but remains free and available for other purposes, such as to bind nanoparticles or other molecules into the gel structure.

Highly Ordered Monolayers of an Optically Active Amphiphilic Pyrene Derivative at the Air–Water Interface
To study the possibility of controlling molecular assemblies such as monolayers by using chirality, we synthesized 1-[1-(6-stearyl)pyrenyl]ethanol (SP6E), a novel amphiphilic molecule with a chiral center in the hydrophilic part and a pyrene ring in the long-chain alkyl backbone. The structures of the racemic and optically active monolayers of SP6E were characterized using the π–A isotherm and analyzed
