The synthesis of spiropyrans was improved significantly with use of ultrasonic radiation. To show the broad applicability of this methodology a range of spiropyrans were prepared which are equipped with iodo, hydroxyl, ethinyl, or azido groups as potential building blocks for conjugation to functional ?-systems or biopolymers. Representatively, the conjugation chemistry was demonstrated for the preparation of spiropyran conjugates with pyrene, perylene, and nile red via the lick-type cycloaddition. These molecular dyads were characterized by optical spectroscopy.
