The synthesis of diblock as well as gradient copolymers of N,N-diethyl glycidyl amine (DEGA) with ethylene oxide (EO) via anionic ring-opening polymerization is presented. The polymers exhibit low polydispersities (≤1.13) and molecular weights in the range of 3300-10 200 g mol(-1) . In PEG-co-PDEGA copolymers, incorporation of 4%-29% DEGA results in tailorable cloud point temperatures in aqueous solution and melting points depending on DEGA content. mPEG-b-PDEGA block copolymers can be quaternized to generate cationic double-hydrophilic polyelectrolyte copolymers with polyether backbone. Furthermore, mPEG-b-PDEGA has been used as dual reducing and capping agent for gold nanoparticle synthesis., (Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.)

Hybrid conjugated polymers containing carborane directly bonded in the aromatic backbone repeat structure have interesting electronic bonding structures and are potentially useful new materials in organic electronics. Conjugated polymers based on o-carborane are particularly interesting for applications in sensing and detection because of the cage's unique bonding scheme and its bent geometry. Poly(fluorene) containing o-carborane displays multiple emission pathways that can be modulated through interactions with small molecules. In this paper, we report that films of poly(fluorene) with o-carborane in the backbone function as vapochromatic photoluminescent sensors toward volatile organic molecules., (© 2011 American Chemical Society)
