Precise synthesis of sulfur-containing polymers via cooperative dual organocatalysts with high activity
Metal-free and controlled synthesis of sulfur-containing polymer is still a big challenge in
polymer chemistry. Here, we report a metal-free, living copolymerization of carbonyl sulfide
(COS) with epoxides via the cooperative catalysis of organic Lewis pairs including bases (e.g.:
phosphazene, amidine, and guanidine) and thioureas as hydrogen-bond donors, afford welldefined poly(monothi...

【Polymers】Iminopyridine-Based Cobalt(II) and Nickel(II) Complexes: Synthesis, Characterization, and Their Catalytic Behaviors for 1,3-Butadiene Polymerization
A series of iminopyridine ligated Co(II) (1a–7a) and Ni(II) (1b–7b) complexes were synthesized. The structures of complexes 3a, 4a, 5a, 7a, 5b, and 6b were determined by X-ray crystallographic analyses. Complex 3a formed a chloro-bridged dimer, whereas 4a, 5a, and 7a, having a substituent (4a, 5a: CH3; 7a: Br) at the 6-position of pyridine, producing the solid structures with a single ligand coo...

53. Controlled Growth of Well-Defined Conjugated Polymers from the Surfaces of Multiwalled Carbon Nanotubes: Photoresponse Enhancement via Charge Separation
The installation of heterojunctions on the surfaces of carbon nanotubes (CNTs) is an effective method for promoting the charge separation processes needed for CNT-based electronics and optoelectronics applications. Conjugated polymers are proven state-of-the-art candidates for modifying thesurfaces of CNTs. However, all previous attempts to incorporate conjugated polymers to CNTs resulted in unord...

34. Enhanced photoresponse of large-sized photoactive graphene composite films based on water-soluble conjugated polymers
Composite films of chemically converted graphene (CCG) and water-soluble polythiophenes (P3TOPS and P3TOPA) were prepared by a LBL method using a suspension of negatively charged CCG-P3TOPS sheets and a solution of positively charged P3TOPA. The composite films show enhanced photoresponsedue to photoinduced electron transfer from the polythiophenes to CCG.

69. [Carbohydrate Polymers] Tough, sticky and remoldable hydrophobic association hydrogel regulated by polysaccharide and sodium dodecyl sulfate as emulsifiers
Hydrophobic association hydrogels have been extensively studied during the past decades. However, the fracture
stress of hydrophobic association hydrogels obtained with anionic surfactants (such as sodium dodecyl sulfate)
achieved hundreds of Pascal. In this investigation, combined surfactants consisting of polysaccharide (gum
arabic) and sodium dodecyl sulfate were utilized to stabiliz...

116.Multi-POSS cluster-wrapped polymers and their block copolymers with a PEO bottlebrush polymer: synthesis and aggregation
In this paper, we report an approach for synthesizing multi-cluster-wrapped polymers and their block copolymers with a bottlebrush polymer with controlled chain length and composition via living ringopening metathesis polymerization. To wrap more than one cluster on a polymer backbone, two to four polyhedral oligomeric silsesquioxane (POSS) clusters were firstly placed at the periphery of low-ge...

A Smart H2O2-Responsive Drug Delivery System Made by Halloysite Nanotubes and Carbohydrate Polymers
A novel chemical hydrogel was facilely achieved by coupling 1,4-phenylenebisdiboronic acid-modified halloysite nanotubes (HNTs-BO) with compressible starch. The modified HNTs and prepared hydrogel were characterized by solid-state nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and transmission electron microscope (TEM). The li...

A well-defined amphiphilic polymer co-network from precise control of the end-functional groups of linear RAFT polymers
Linear polystyrene (PS) with well-defined molecular structure and accurate numbers of bromo groups on both ends were synthesized via multiple-step alternative RAFT polymerization of N-bromopropyl maleimide and bpinene monomers. The bromo end groups were transformed into the azido moieties via nucleophilic substitution. The reaction of as-synthesized linear PS having a named number of azide group...
