General description

8-Quinolinol (QOH) forms complexes with heavy metals [Pt(II), Pb(II), Bi(III), Ir(III)]. These complexes show long-lived phosphorescence and excited state absorption in solutions. It has been reported to form metal chelate complexes. Immobilized 8-quinolinol has been widely used in the preconcentration step during the extraction of metals.
