The reaction of mercury(II) halides with 1,2-bis(diphenylphosphino)ethane monoxide (dppeO) in 1:1 molar ratio yielded P,O-coordinated polymers having the empirical formula [HgX2(dppeO)]n [X = Cl (1), Br (2), I (3)]. In contrast, the reaction between the sa ...
The term polymer brush refers to a well defined arrangement of polymer chains, which are tethered with one end to an interface and usually the surface of a solid substrate. Due to steric repulsion the polymer chains furthermore adopt a defined, stretched c ...
Novel amphiphilic multi-arm star-block copolymers with a hyperbranched core, a hydrophobic inner shell, and a hydrophilic outer shell have been prepared from a commercial hyperbranched polyester macroinitiator by ring-opening polymerization of -caprolacton ...
Effective encapsulation of small, volatile, weakly water-soluble molecules such as flavors and fragrances is necessary to protect them from degradation, to increase their lifetime, and to improve their water dispersion and fixation depending on the substra ...
The operating mechanism, particularly the carrier injection mechanism, of a hybrid organic-inorganic light-emitting diode (HOILED) is reported. Asymmetric hole injection has been observed in a symmetric hole-only device, which has two identical interfaces ...
Peptide based and peptide hybrid materials represent two interesting and challenging classes of biomaterials. Both classes consist of and contain, respectively, one or more polypeptide blocks, endowing the resulting polymers with enhanced self-assembly pro ...
Unlike traditional pressure sensitive adhesives, the natural setal arrays of gecko lizards achieve dry adhesion with stiff, keratinous material. This remarkable property has inspired a new class of adhesive and high friction microstructures composed of sti ...
We present new polymeric amphiphiles derived from N-acryloyl derivatives of the cyclic secondary amines: morpholine, piperidine, and azocane polymerized by reversible addition -fragmentation transfer (RAFT) polymerization. Both homopolymerization and block ...
Throughout these last years, many synthetic polymers have been developed for non-viral gene delivery systems in attempt to overcome potential shortcomings of viral vectors. However, it is still difficult to achieve highly efficient transfection under physi ...
The three-component reaction of aryl boronic acids with 1,2,4,5-tetrahydroxybenzene and 1,2-bis(4-pyridyl)ethylene or 4,4-bipyridine leads to the formation of dark-purple boronate ester polymers. Crystallographic analyses show that the polymer strands have ...
