Effective enantioselective recognition by steady-state fluorescence spectroscopy: Towards a paradigm shift to optical sensors with unusual chemical architecture

Photoactive glycoconjugates with a very large Stokes shift: synthesis, photophysics, and copper(ii) and BSA sensing

“…However, previous studies have shown that for similar benzazole systems containing chiral substituents, although the compounds also did not exhibit significant differences in the absorption and/or fluorescence emission spectra as observed in our investigation, they were able to show specific interactions with chiral analytes, enabling different photophysical responses, which were used for their enantioselective recognition. 57 These results corroborate the potential use of these compounds in the sensitization of different analytes.…”

Rotamer-Controlled Dual Emissive α-Amino Acids

“…We recently reported the synthesis and development of several new classes of unnatural α-amino acids, 11 including compounds with biaryl benzotriazole-derived side chains that displayed charge transfer fluorescence ( Figure 1 c). 12 To achieve dual emission via LE and TICT states, we proposed that modification of the benzotriazole 13 side chain to a benzotriazinone motif would allow both flexibility and enhanced charge transfer properties. The motivation for developing dual emission amino acids of this nature was the potential to use the different sensitivities of the LE and TICT bands to polarity and pH to report environmental changes.…”
