In the structure of the title coordination polymer, [K(C(8)H(5)N(2)O(6))](n), each ligand bridges six K(+) cations. The carboxyl-ate group coordinates both bidentately to one K(+) ion and monodentately to two K(+) ions, while one nitro group coordinates bidentately to a fourth K(+) ion. The last two K(+) ions are coordinated by the remaining nitro group, one in a bidentate fashion, the other mo...
The adsorption of amphiphilic poly(ethylene oxide)-b-poly(epsilon-caprolactone) and poly(ethylene oxide)-b-poly(gamma-methyl-epsilon-caprolactone) copolymers in aqueous solution on silica and glass surfaces has been investigated by flow microcalorimetry, small-angle neutron scattering (SANS), surface forces, and complementary techniques. The studied copolymers consist of a poly(ethylene oxide) ...
Abstract Herein, the synthesis of three different macromolecular DO3A@Gn conjugates based on poly(2‐oxazoline)s is presented. Therefore, poly(2‐methyl‐2‐oxazoline) synthesized by a ring‐opening, cationic polymerization and terminated with DO3A( t Bu) 3 . The best results are obtained after 48 h at 120 °C degree termination 86%. After deprotection DO3A ligand complexation Gn 3+ , relaxivity as m...
