Platinum (Pt)-containing novel conjugated polymers, poly(1-2a)-poly(1-2d) having bipyridine ligands were synthesized by the Sonogashira-Hagihara coupling polymerization of [Pt(4,4′-dibromo-2,2′-bipyridine)((R,R)-2,3-bis(tert-butylmethylphosphino)quinoxaline)(trifluoromethanesulfonate)2] (1) coordinated with 4,4′-dibromo-2,2′-bipyridine/(R,R)-2,3-bis(tert-butylmethylphosphino)quinoxaline [(R,R)-QuinoxP*] and 1,4-diethynylbenzene (2a), 1,4-diethynyl-2,5-bis(heptyloxy)benzene (2b), 1,4-diethynyl-2,5-bis(2-ethylhexyloxy)benzene (2c), and 1,4-diethynyl-2,5-bis(2-(2-methoxyethoxy)ethoxy)benzene (2d). Poly(1-2d) exhibited CD signals derived from (R,R)-QuinoxP* and the conjugated main chain around 290 and 440 nm in DMF, resp. The simulated CD spectroscopic pattern of a low mol. model compound, M1-Pt, agreed well with the observed spectra. The TEM images of poly(1-2d) in the solid state exhibited dispersed patterns with sizes around 10 nm. Concentrated solutions of polymer 1-2d in DMF and CHCl3 partly exhibited patterns assignable to the formation of lyotropic liquid crystals. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Recommanded Product: 111-77-3).
2-(2-Methoxyethoxy)ethanol (cas: 111-77-3) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Recommanded Product: 111-77-3
