Novel scorpion type phthalocyanine chemosensors for detection of selective-metal ion by inducing H- and J-aggregations in solution; synthesis, characterization and electrochemistry

摘要: Abstract Scorpion type metal(II) and metal(III) phthalocyanine reversible sensors, MPc[ β -[dihydroxypropylthio] 8 ]X [where M = 2H( 2 ), Cu(II)( 3 Co(II)( 4 Mn(III)( 5 ) or Pb(II)( 6 ); X = Cl only when M = Mn(III)] have been prepared for detection of selective soft metal ion from the corresponding salts 4,5-bis-(1,2-dihydroxy propylthio)-phthalonitrile compound ( 1 ). Upon addition Ag(I), Pd(II), Zn(II), Ni(II), Na(I) Mg(II) ions into solution , in THF, Pd(II) Ag(I) result particular responses pronounced Q- B-bands their UV–Vis spectra as a donor–acceptor interactions. The novel compounds characterized by using MALDI-TOF MS, FT-IR, UV–Vis, H NMR, 13 C AFM elemental analysis. In based electron transfer reactions observed to common ring-based processes. case stable anionic species without demetallation Pb(II).
