A series of water-soluble and cationic methoxy poly(ethylene glycol)-b-poly(g-amino-3-caprolactone) (mPEG-b-PACL) has been synthesized via ring opening polymerization of g-(carbamic acid benzyl ester)-3-caprolactone (gCAB3CL) using mPEG as a macroinitiator and Sn(Oct)2 as a catalyst, and subsequent hydrolysis of the Cbz protecting groups under acidic conditions. The well-defined structure
of copo...

In this paper, aliphatic polyesters functionalized with pendant carboxylic groups were synthesized via several steps. Firstly, substituted cyclic ketone, 2-(benzyloxycarbonyl methyl)cyclopentanone (BCP) was prepared through the reaction of enamine with benzyl-2-bromoacetate, and subsequently converted into the relevant functionalized δ-valerolactone derivative, 5-(benzyloxy carbonylmethyl)-&...

A facile hard-templating route has been successfully developed to fabricate uniform hollow mesoporous silica spheres and ellipsoids by using hematite as hard template. The outer diameter of the spherical mesoporous silica particles can be well adjusted in a sub-micrometric range (typically around 100–200nm) by selecting suitable hematite particles as core templates. The thickness of the meso...

The electron-withdrawing groups (EWGs) in the electrophilic alkenes employed in the Michael addition reaction are almost only CO2R, CN, COR, NO2, and SO2Ph. Although amides (CONR1R2) are also typical electron-withdrawing groups and are of great importance in organic synthesis, they are scarcely employed as the EWGs of the electrophilic alkenes in the Michael addition reaction. In this work, the Mi...

Poly(ethylene oxide) containing azo groups (pre-PEO) was prepared by reacting azoisobutyronitrile (AIBN) with poly(ethylene oxide) (PEG). The molecular weight of pre-PEO was depended on the reaction time, the ration of PEG to AIBN and the molecular weight of PEG. Pre-PEO decomposed in the presence of butylacrylate (BA) monomer to from poly(ethylene oxide-block-butylacrylate) copolymers (PEO-b-PBA)...

Metallocenium Chemistry and Its Emerging Impact on Synthetic Macromolecular Chemistry
Cationic metallocenes (or metalloceniums) are a class of sandwich-type compounds with cationic metal centers, which are usually iron, cobalt, or rhodium. These unique charged complexes have received wide attention owing to both rich electrochemistry and the positive charge associated with the transition metal. They are potential building blocks for fabricating functional polyelectrolytes an...
