Luo, Qi published the artcileSynthesis of Metal-Containing Poly(thiophene methines) via Solid- and Melt-State Polymerization and Their Related Applications as Highly Sensitive Ni2+ Chemosensors, Name: 2-Bromo-3-(2-ethylhexyl)thiophene, the publication is Organometallics (2019), 38(3), 647-653, database is CAplus.
Metal-containing polymers have attracted continuous interest, for they combine the features of a metal complex and a polymer. Here, a series of thiophene methine based phenanthroline ligands (L1–L4) and their metal (Zn(II) and Cd(II)) complexes were prepared as monomers. Accordingly, metal-containing poly(thiophene methines) were prepared from these metal complexes via solid- and melt-state polymerization (S(M)SP). The polymerization process was preliminarily investigated by a crystal structure study, NMR anal., and absorbance spectra. Furthermore, the metal-free polymer (PL4) prepared directly from the ligand via MSP was tested as a metal ion chemosensor, which showed good selectivity and excellent sensitivity toward Ni2+ with a detection limit of 4.1 × 10-9 M.
