“…They were thymine‐2,4‐diaminotriazine (Thy‐Tr) or 2‐ureido‐4[1 H ]‐pyrimidinone‐2‐ureido‐4[1 H ]‐pyrimidinone (UPy‐UPy) interactions for the reports discussed here. These hydrogen bonding interactions were confirmed by FTIR . Studies have shown that these hydrogen bonding interactions are dominant at low molecular weights of at least one of the blocks and that the hydrogen bonding has a confining effect.…”

Block copolymers (BCPs) are important for technological advances in numerous industries, including but not limited to, electronics, biomedical, optics, environmental, and infrastructure. Because of their ubiquity, it is important to understand their hierarchical phase behavior to tune their macroscopic properties for efficient use. These macroscopic properties are derived from the microscopic self‐assembled structures. One unique form of hierarchical assembly exists when one or more of the polymeric blocks form lamellar crystals. These crystals are integral to understanding and predicting the macroscopic behavior. This review reports on recent advances in crystallization of BCPs, including bulk and solution assembly. Reports highlighting development in fundamental processes regarding crystallization mechanisms and behavior as well as for the design of practical applications are included.

A novel and efficient strategy in obtaining series of mono-and bi-armed azobenzene-containing poly(3-caprolactone)s is described, starting from a commercially available azobenzene dye via azide/alkyne-"click"-reactions. The attachment of alkyne-telechelic poly(3-caprolactone)s (1 kDa and 3 kDa), followed by chromatographic separation, allowed the attachment of either one or two PCl-chains to either side of the azobenzene-dye. The resulting mono-and bi-armed photo-switchable polymers are fully characterized by 2D-NMR techniques and show a high thermal stability. Additionally liquid chromatography at critical conditions (LCCC) coupled to ESI-TOF allowed us to prove the presence of either one or two polymer chains affixed onto the central azobenzene dye.

Self-assembly has been a powerful method to fabricate the polymer materials with well-defined structures and morphologies. Such assembled materials have shown wide potential applications in many fields such as nanomaterial, nanomedicine, lithography, and microelectronic. Crystallization has been a general behavior of stereoregular polymers. Besides the various noncovalent interactions, crystallization of polymer blocks or end groups can be an efficient way to manipulate the self-assembly pathway and assembled structures of polymers in both solid and solution. Crystallization-driven self-assembly has been widely implemented for the semicrystalline block copolymers (BCPs) and end-functionalized polymers. This minireview briefly presents the recent progresses in the crystallization-driven self-assembly of BCPs and endfunctionalized polymers in both solid and solution states. Formation process, mechanism, and hierarchical structure of the crystallization-induced assemblies for BCPs and end-functionalized polymers are highlighted.
