Incorporation of 2-Pyrone Skeleton into Polyamide Containing a Five-Membered Lactone Unit in Main Chain.

Preparation and Chemical Properties of π-Conjugated Polymers Containing Indigo Unit in the Main Chain

π-Conjugated polymers based on indigo unit were prepared. Dehalogenative polycondensation of N-hexyl-6,6'-dibromoindigo with a zerovalent nickel complex gave a homopolymer, P(HexI), in 77% yield. Copolymer of N-hexyl-indigo and pyridine, P(HexI-Py), was also prepared in 50% yield. P(HexI) showed good solubility in organic solvents, whereas P(HexI-Py) was only soluble in acids such as HCOOH. The...

A Survey of Anticancer Effect of Some Five- and Six-Membered Palladium (II) Complexes (Containing Bidentate Phosphorus Ligands) on Caco-2 Colon Cancer Cell Line
