Although shape memory polymers have been highlighted widely and developed rapidly, it is still a challenging task to realize complex temporary shapes automatically in practical applications. Herein, a novel shape memory hydrogel with the ability of self‐defor...

Glycidyl Triazolyl Polymers: Poly(ethylene glycol) Derivatives Functionalized by Azide–Alkyne Cycloaddition Reaction

10.1002/marc.201700825

2018-03-12

Glycidyl triazolyl polymer (GTP), which is the product of the Huisgen dipolar cycloaddition reaction between glycidyl azide polymer and alkyne derivatives, is featured here. GTP is the multifunctionalized poly(ethylene glycol) (PEG). The drawback of PEG is th...

Chiral Binaphthylbis(4,4′‐Bipyridin‐1‐Ium)/Cucurbit[8]Uril Supramolecular System and Its Induced Circularly Polarized Luminescence

2018-03-12

Circularly polarized luminescence (CPL) induced by host–guest complexation remains a challenge in supramolecular chemistry. Herein, a couple of CPL–silent enantiomeric guest binaphthylbis(4,4′‐bipyridinium) salts can emit obvious CPL in the presence of cucurb...

Aerogels Derived from Polymer Nanofibers and Their Applications

10.1002/marc.201700724

2018-03-08

Aerogels are gels in which the solvent is supplanted by air while the pores and networks are largely maintained. Owing to their low bulk density, high porosity, and large specific surface area (SSA), aerogels are promising for many applications. Various inorg...

Automatically Programmable Shape‐Memory Polymers Based on Asymmetric Swelling of Bilayer Structures

10.1002/marc.201800039

2018-03-08

Shape‐memory polymers (SMPs) possess the capability to change shapes upon stimulation; however, the programming process that determines the temporary shape cannot proceed without external manipulation, which may greatly affect the shape complexity, accuracy, ...

t‐Butyl‐Oxycarbonylated Diamines as Building Blocks for Isocyanate‐Free Polyurethane/Urea Dispersions and Coatings
