Dix, Johannes Peter,Voegtle, Fritz
, p. 638 - 651 (2007/10/02)
The synthesis and spectroscopic properties, especially shifts in light absorption upon addition of salts, of the new ionophore dyes 1, 3, 4, 10, and 11 of the anthraquinone-, naphthoquinone-, and phenol blue type are described.The observed hypsochromic and bathochromic shifts are discussed in view of the crown ether complexation in the donor or acceptor part, resp., or with 3 and 4 in view of the coordination at both donor and acceptor.Influences of the ion size and of the charge density as well as the influence of changes of the cyanine and polyene character are explained.
