Poly(p-phenylene Vinylene) Nanoparticles by Acyclic Diene Metathesis (admet) Polycondensation in Aqueous Emulsion

Chair of Chemical Materials Science, Department of Chemistry, University of Konstanz, Germany Introduction Poly(p-phenylene vinylene) (PPV) and its derivatives are amongst the most widely studied class of conjugated polymers since the discovery of their electroluminescent properties in 1990. These polymers are studied for applications in numerous photonic devices such as organic solar cells, or...

One-pot synthesis of polyrotaxanes via acyclic diene metathesis polymerization of supramolecular monomers.

A one-pot synthesis of polyrotaxanes has been developed. The method employs a supramolecular monomer comprising a polymerizable ammonium salt and crown ether, in combination with dynamic ADMet polymerization. Ultimately, highly efficient complexation, polymerization, and end-capping were accomplished in a single operation to yield polyrotaxanes with M(w) up to 19.3 kDa and >80% of the repeat un...

Acyclic Diene Metathesis (ADMET) Polymerization for Precise Synthesis of Defect-Free Conjugated Polymers with Well-Defined Chain Ends

This accounts introduces unique characteristics by adopting the acyclic diene metathesis (ADMET) polymerization for synthesis of conjugated polymers, poly(arylene vinylene)s, known as promising molecular electronics. The method is more suitable than the other methods in terms of atom efficiency affording defect-free, stereo-regular (exclusive trans) polymers with well-defined chain ends; the re...

Intramolecular Friedel–Crafts acylation of acyclic (h-diene)Fe(CO)3 complexes

Intramolecular cyclization of (h-diene)Fe(CO)3 complexes bearing a carboxylic acid chloride functionality at the terminal side chain of the diene ligand produces (s, h-allyl)Fe(CO)3 complexes, whereas treatment of the acid chloride complexes with Et3N and AlCl3 provides (h-diene)Fe(CO)3 complexes containing a cyclopentanone moiety. © 2000 Elsevier Science S.A.

Recent Applications of Acyclic (Diene)iron Complexes and (Dienyl)iron Cations in Organic Synthesis.

Complexation of (tricarbonyl)iron to an acyclic diene serves to protect the ligand against oxidation, reduction and cycloaddition reactions while the steric bulk of this adjunct serves to direct the approach reagents to unsaturated groups attached to the diene onto the face opposite to iron. Furthermore, the Fe(CO)(3) moiety can serve to stabilize carbocation centers adjacent to the diene (i.e....
