    Maleimide-Functionalized Photochromic Spirodihydroindolizines

    No full text
    Two photochromic spirodihydroindolizine/betaine systems for tethering to peptides and proteins via a maleimide function have been prepared. The absorption spectra of the betaines are in the red region of the visible spectrum and in the near-IR spectral domain, which are suitable energies of light for future in vivo applications. The half-times of cyclization have been determined for both DHI/betaine systems. The findings are consistent with a thermal barrier of varying size between the <i>transoid</i> and <i>cisoid</i> conformers of the betaines
