A long wavelength absorbing cation responsive chromoionophore 1 based on the strongly π-electron accepting dicyanovinylindane subunit and an electron donating N-phenylazacrown ether binding site was synthesized. The absorption spectra of this compound in CH3CN show strong changes in the near-infrared (NIR) spectral range upon binding of cations in the crown-ether moiety.
