“…350 In contrast, L n is expected to increase with the square root of the concentration of unimer in a thermodynamically controlled onedimensional growth that operates under equilibrium conditions, as observed for surfactant based cylindrical micelles.

The self-assembly into supramolecular polymers is a process driven by reversible non-covalent interactions between monomers, and gives access to materials applications incorporating mechanical, biological, optical or electronic functionalities. Compared to the achievements in precision polymer synthesis via living and controlled covalent polymerization processes, supramolecular chemists have only just learned how to developed strategies that allow similar control over polymer length, (co)monomer sequence and morphology (random, alternating or blocked ordering). This highlight article discusses the unique opportunities that arise when coassembling multicomponent supramolecular polymers, and focusses on four strategies in order to control the polymer architecture, size, stability and its stimuli-responsive properties: (1) endcapping of supramolecular polymers, (2) biomimetic templated polymerization, (3) controlled selectivity and reactivity in supramolecular copolymerization, and (4) living supramolecular polymerization. In contrast to the traditional focus on equilibrium systems, our emphasis is also on the manipulation of selfassembly kinetics of synthetic supramolecular systems. V C 2016

“…Just above critical micelle concentration (CMC), micelles are generally spherical in shape 14) . With change of a control parameter such as composition, temperature, or other external parameters, the micelles often grow into long cylindrical micelles [15][16][17] . These cylindrical micelles under a certain condition of temperature, concentration or salinity can be entangled with each other and form wormlike micelles [18][19][20][21] .…”

Structure of diglycerol monolaurate (abbreviated as C 12 G 2 ) micelles in nonpolar oils cyclohexane and n-octane as a function of compositions, temperatures, and surfactant chain length has been investigated by small-angle X-ray scattering (SAXS). The SAXS data were evaluated by the generalized indirect Fourier transformation (GIFT) method and real-space structural information of particles was achieved. Conventional poly(oxyethylene) type nonionic surfactants do not form reverse micelles in oils unless a trace water is added. However, present surfactant C 12 G 2 formed reverse micelle (RM) in cyclohexane and n-octane without addition of water at normal room temperature. A clear signature of one dimensional (1-D) micellar growth was found with increasing C 12 G 2 concentration. On the other hand, increasing temperature or hydrocarbon chain length of surfactant shorten the length of RM, which is essentially a cylinder-to-sphere type transition in the aggregate structure. Drastic changes in the structure of RM, namely, transition of ellipsoidal prolate to long rod-like micelles was observed upon changing oil from cyclohexane to octane. All the microstructural transitions were explained in terms of critical packing parameter.

“…There are many ways to theoretically deal with linear self-assembly [36,[38][39][40][41][42][43][44][45][46][47]. In the simplest Ansatz, the aggregation depends solely on a single energetic parameter, describing the free energy expended to break an aggregate into two.…”
