Synthesis and characterization of poly(phenylacetylene)s with Ru(II) bis-terpyridine complexes in the side-chain.

An alkyne-functionalized ruthenium(II) bis-terpyridine complex is directly copolymerized with phenylacetylene by alkyne polymerization. The polymer is characterized by size-exclusion chromatography (SEC), (1) H NMR spectroscopy, cyclic voltammetry (CV) measurements, and thermal analysis. The photophysical properties of the polymer are studied by UV-vis absorption spectroscopy. In addition, spectro-electrochemical measurements are carried out. Time-resolved luminescence lifetime decay curves show an enhanced lifetime of the metal complex attached to the conjugated polymer backbone compared with the Ru(tpy)2 (2+) model complex.

Fluorescent monomers as building blocks for dye labeled polymers: synthesis and application in energy conversion, biolabeling and sensors.

This review focuses on side-chain functionalized polymers derived from direct (co)polymerization of fluorescent dyes. This overview about polymerizable dyes includes 1,8-naphthalimides, fluoresceins, rhodamines, coumarins, azo-dyes, oxadiazoles, diverse aromatic dyes as well as selected other dyes that cannot be classified within these groups. The discussed dyes have been functionalized with a polymerizable unit in order to apply straight-forward polymerization procedures. Therefore, the center of attention is set to the optical properties of the polymerizable dyes and the applicable polymerization techniques. Furthermore, the various applications (i.e., in biomedicine and pharmacy, as thermo-responsive materials and energy transfer materials, for dispersion of carbon nanotubes and others) of each polymer are discussed.
