Description:
<jats:title>Abstract</jats:title><jats:p>Various fulgides based on benzofuryl and indolyl core units with versatile functionalities were synthesized. Substitution at the phenylic site shows only small effects on the photochromic properties compared to the parent compounds <jats:bold>30</jats:bold> and <jats:bold>31</jats:bold>. Fulgide–dye conjugates were prepared based on anthryl and coumaryl moieties. Fluorophores were introduced to the fulgide via substitution reaction or copper‐catalyzed azide‐alkyne cycloaddition (CuAAC). The synthesized conjugates show weak fluorescence and quenching properties in solution.</jats:p>
