Responsive Composite Janus Cages

引用

Chinese Journal of polymer Science 2015年第10期33卷 1462-1469页

作者： Qi-guang Wang 梁福鑫 Qian Wang Xiao-zhong Qu 杨振忠 state key laboratory of polymer physics and chemistry Institute of Chemistry Chinese Academy of Sciences

pH responsive composite Janus cages of PS-silica-PEO are prepared using silica nanoparticles to crosslink two PAA contained di-block copolymers at an emulsion interface sequentially. Transverse channels are in situ created across the shell, which facilitates mass transfer. Shell is pH responsive owing to the presence of residual PAA chains tethered onto the silica nanoparticles. The Janus cages are capable to preferentially capture oil from their aqueous surroundings. The saturation absorption capacity is determined by pH and oil property. Other composite Janus cages are expected by extension the method using other copolymers and functional nanoparticles.

One-dimensional Janus polymeric Vehicles

Chinese Journal of polymer Science 2015年第9期33卷 1344-1350页

作者： Dong-mei Lv Wei Ni 梁福鑫 Qian Wang Xiao-zhong Qu 杨振忠 state key laboratory of polymer physics and chemistry Institute of Chemistry Chinese Academy of Sciences

We herein report a novel approach to fabricate poly（DVB-co-VBC） one-dimentional nanomaterials with varied composition. By adjusting the monomer DVB/VBC ratio and using inert solvents, after internal cavity of the nanotubes disappears and length of the nanotubes is decreased, thus nanorods are achieved. After quaternary ammoniation from the benzyl chloride group, the exterior surface becomes hydrophilic while the interiority preserves hydrophobic. The Janus nanorods can serve as a specific vehicle to selectively collect oils from their aqueous surroundings.

A mononuclear complex, cis-1,10-phenanthroline-palladium(Ⅱ)(THF)2]dinitrate (THF = tetrahydrofuran) [Pd(C10H8N2)(C4H8O)2](NO3)2 1, has been prepared and structurally characterized by single-crystal X-ray diffraction. The crystal belongs to monoclinic system, space group P21/c with a = 7.881(1), b = 27.371(3), c = 10.178(1) ? ?= 103.313(3)? V = 2136.5(4) 3, Mr = 554.83, Dc = 1.725 g/cm3, Z = 4, F(000) = 1128 and (MoK) = 0.926 mm-1. The structure was refined to R = 0.0678 and wR = 0.1651 for 1687 observed reflections with I > 2(I). It is revealed that the central Pd(Ⅱ) ion in the title complex is bonded to two THF and two phenanthroline molecules in a cis-configuration to form the coordination geometry, deviating slightly from the square plane.
