But in real samples several different analytes have to be detected at the same time.…”

“…128 To overcome the above mentioned shortcomings of probe 10 we turned our attention to crown-ether functionalities as receptor units, because it has been demonstrated already with numerous examples that the direct attachment of azacrown ether units to a fluorophore is a general design principle for the development of donor-acceptor based fluorescent probes that change emission wavelength upon complexation of a metal ion (Scheme 1c). [3][4][5][6][7][8][9][10][11][12][122][123][124][125][126][127] Nevertheless, most crown ether host molecules do not bind the analyte to significant extent in water, 129 so that the majority of probes can only operate in non-competitive organic solvents. Therefore, we focused our studies on the 1,4-dioxa-7,13-dithia-10-azacyclopentadecane receptor unit, that is known to bind Hg 2+ ions in water with high affinity.…”
