Capsule-shaped molecular receptors are fundamental to the modeling of biological host– guest interactions such as those characteristic of enzymatic processes. Among the more versatile and effective synthetic receptors are the hemicarcerand-type hosts. Herein we report the synthesis of six novel resorcin [4] arene cavitand-capped porphyrin capsules, in a new series of molecular capsules modeled on the classical hemicarcerands initially ...
