Safety of 2-(Thiophen-3-yl)-1,3-dioxolaneOn September 30, 2008 ,《The effects of pendant vs. fused thiophene attachment upon the luminescence lifetimes and electrochemistry of tris(2,2′-bipyridine)ruthenium(II) complexes》 was published in European Journal of Inorganic Chemistry. The article was written by Nurkkala, Lasse J.; Steen, Robert O.; Friberg, Henrik K. J.; Haeggstroem, Johanna A.; Bernhardt, Paul V.; Riley, Mark J.; Dunne, Simon J.. The article contains the following contents:
The electrochem. and photophys. properties for a range of tris(2,2′-bipyridine)ruthenium(II) complexes in which a thiophene substituent is attached to one of the bipyridine ligands by either a pendant or a fused mode were determined The fused mode of attachment eliminates torsional movement between the thiophene unit and the chelating bipyridine, thereby offering optimal overlap between the π-systems of the chelating unit and the attached thiophene unit. The electrochem. properties of these complexes are similar; however, the luminescence lifetimes and intensities (in CH3CN at room temperature) are correlated to the mode of attachment. The longest luminescence lifetime was observed for [Ru(bpy)2{4-(thiophen-2-yl)-2,2′-bipyridine}]2+ (3000 ns), as compared to the prototypic [Ru(bpy)3]2+ (1745 ns). This complex also had the highest quantum yield (0.045). In the four isomeric complexes, where the thiophene ring was fused to the b or c face of the pyridine ring, the lifetimes fell in the interval 275-1510 ns, and the quantum yield ranged between 0.0047 and 0.014. In addition to this study using 2-(Thiophen-3-yl)-1,3-dioxolane, there are many other studies that have used 2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3Safety of 2-(Thiophen-3-yl)-1,3-dioxolane) was used in this study.
2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3) is one of dioxolane. 1,3-Dioxolane derivatives are recognized as important motifs for the construction of numerous pharmacologically active molecules as antiviral, antifungal, anti-HIV, and adrenoreceptor antagonists.Safety of 2-(Thiophen-3-yl)-1,3-dioxolane
