A New Type of Cation Responsive Chromoionophore with Spectral Sensitivity in the Near-Infrared Spectral Range
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-infrare...

| Zusammenfassung: | 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. |
