Kadarkaraisamy M, Sykes AG: Luminescence detection of transition and heavy metals by inversion of excited states: synthesis, spectroscopy, and X-ray crystallography of Ca, Mn, Pb, and Zn complexes of 1,8-anthraquinone-18-crown-5. Inorg Chem. 2006 Jan 23;45(2):779-86.
Photophysical properties and binding constants of this new class of luminescence sensors are provided, as well as the X-ray crystallographic results for Pb (2+), Mn (2+), and Zn (2+) complexes of 1,8-oxybis (ethylene-oxyethyleneoxy) anthracene-9,10-dione (1), referred to as 1,8-anthraquinone-18-crown-5.
