The synthesis and characterization of a series of poly(3-allcyltellurophene)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 examples exhibit red-shifted optical absorption, as well as solid-state organization, as evidenced by absorption spectroscopy and atomic force microscopy. Overall, the synthesis and characterization of these materials open up a wide range of future studies involving tellurium-based polyheterocycles.
Multiple investigations of aqueous Eu(<scp>iii</scp>)–oxalate complexes: the reduction in coordination number and validation of spectral linear correlation
linear correlation between the luminescence lifetime and the residual hydration number in the first coordination sphere of Eu(III) compounds in solution, a comparison between the spectral results and the theoretical calculations in a wide parametric space in terms of the pH value and oxalate concentration was carried out by combining time-resolvedluminescencespectroscopy (TRLS) with speciation modelling
