Summary: An organocatalytic controlled/living ring-opening polymerization method was developed for the precise synthesis of linear poly[phenyl(p-tolyl)siloxane] (PPTS) with controlled M-n, D-M, and targeted terminal structures. The synthesis of PPTS and triblock copolymer PPTS-b-PDMS-b-PPTS showed good solubility in various organic solvents and high heat resistance and fusibility in thermal analysis.

Summary: By controlling the composition of the copolymers with octadecyl groups and hydroxyethyl groups in solution, ordered lamellar structures can be formed in the solid state, while spin-coating the polymer solutions onto silicon substrates allows the copolymers to autonomously form multilayered lamellar thin films.

Summary: This report discusses the use of enyne-containing branching agents in synthesizing star and miktoarm star polymers through a convergent synthesis pathway using ring-opening metathesis polymerization (ROMP). By introducing these agents into a living ROMP, control over the degree of polymerization of the star arms, the number of star arms, and chain extension can be achieved to produce functional asymmetric miktoarm star polymers.

Summary: Bifunctional initiators were used to synthesize complex triblock copolymer structures in carbanionic polymerization. Isoprene was polymerized using 1,3-bis(1-phenylethenyl)benzene (PEB), resulting in a high content of 93% 1,4-PI units. Hydroxyl groups were then introduced simultaneously in the alpha- and omega-position using end-functionalization of the living anionic di-lithiated polyisoprene (PI) chains with 1,2-isopropylidene glyceryl glycidyl ether (IGG) and subsequent acidic deprotection. The resulting hexa-hydroxy functional PI-macroinitiators were used to initiate l-lactide (LLA) polymerization, leading to the formation of super-H-shaped (PLLA)(3)-b-PI-b-(PLLA)(3) triblock structures with narrow molecular weight distributions.

Summary: A defined three-dimensional nanoparticle assembly within unit cells can be achieved by linking nanoparticles to block copolymers. The study shows that the block length ratio and interfacial curvature are crucial factors determining lattice type, with even a one percent volume fraction enough to destabilize the structure and favor the formation of highly curved interfaces. This research paves the way for functional 3D-nanocomposites with nanoparticles located on specific matrix positions.

Summary: A class of amino acid-based low-molecular-weight gelators were used to study the tunable optical properties and self-assembly process of single and multicomponent gels. The optical properties of multicomponent gels were easily tuned by changing component proportions, with transparency attributed to changes in fiber diameters. The structural similarities of molecules in the gel phase favored coassembly packing over self-sorting, and molecular packing in the crystalline phase was found to translate into the gel network structure.

Summary: Researchers have successfully reported a shape-memory photonic crystal thermoplastic (CNC-SMP) utilizing chiral nematic cellulose nanocrystals embedded in a polyacrylate matrix, allowing reversible capturing of different colored states through temperature programming and pressure adjustment. The material can transition its structural color from red to blue with increased force, and recover to its original state by heating it above the glass transition temperature. Additionally, multicolor readouts can be programmed into the material, and the glass transition temperature can be tuned by altering the monomer composition.
