Poly(3-alkyltellurophene)s Are Solution-Processable Polyheterocycles

Journal of the American Chemical Society, 2013
The synthesis and characterization of a series of poly(3-alkyltellurophene)s are described. Polymers are prepared by both electrochemical and Kumada catalyst transfer polymerization methods. These polymers have reasonably high molecular weights (M(n) = 5.4-11.3 kDa) and can be processed in a manner analogous to that of their lighter atom analogues. All

Chemistry of Organic Polyheterocyclic Conductors

Israel Journal of Chemistry, 1986
AbstractThe synthesis and some properties of polymeric heterocycles as well as the latest results in the area of soluble conducting polymers are reviewed. Polyheterocycles with long chain substituents exhibit unusual properties in solution while retaining a relatively high conductivity in the solid state.

Novel alicyclic dianhydrides and polyheterocycles on their basis

Makromolekulare Chemie. Macromolecular Symposia, 1991
AbstractDianhydrides of alicyclic tetracarboxylic acids were synthesized by chemical modification of tri‐cyclodecenetetracarboxylic dianhydride and its chloro‐containing derivatives. By polycondensation of these di‐anhydrides with diamines polyimides were obtained. Thermal and thermooxidative degradation of these polyimides are discussed.

Thermoplastic polyheterocycles. II: Polyalkylene‐imides

Polymer Engineering & Science, 1994
AbstractPolyalkylene‐imides (i.e., aliphatic‐aromatic polyimides) were prepared smoothly in N‐methyl pyrollidone from straight chain aliphatic diamines and pyrromellitic dianhydride. Melting points of the polymers ranged from about 300 to 450°C, depending of the length of the alkylene chains.

Synthesis and antifungal activities of novel polyheterocyclic spirooxindole derivatives

Organic & Biomolecular Chemistry, 2015
A series of spirooxindole tetrahydrofuran derivatives were obtained in moderate to good yields via base-mediated cascade [3+2] double Michael reactions under mild conditions. Their antifungal effects on selected five target phytopathogenic fungi were investigated, and their structure ...

Green Multicomponent‐Click Strategy for One‐Pot Synthesis of Polyheterocyclic Estazolam Aza‐Analogs and Their Symmetrical Polyheterocycles

Asian Journal of Organic Chemistry
ABSTRACT A novel one‐pot synthesis of polyheterocyclic compounds (PHCs) incorporating fused 1,5‐disubstituted 1,2,3‐triazole‐1,4‐benzodiazepines (fused 1,5‐Ds‐1,2,3‐T‐1,4‐BZD) bound to 1,5‐disubstituted tetrazoles (1,5‐Ds‐Ts) was developed via Ugi‐azide four‐component reaction (UA‐4CR), followed by an intramolecular alkyne–azide ...

Use of the quartz microbalance in the study of polyheterocycle electrosynthesis

Synthetic Metals, 1989
Abstract An electrochemical quartz crystal microbalance has been used to study the anodic electropolymerization and concurrent deposition of polypyrrole onto gold in acetonitrile and propylene carbonate using tetraethylammonium tosylate, tetrabutylammonium fluoroborate, and lithium perchlorate.
