“…The fabrication of these hierarchically organized photoactive materials and their use as artificial antenna systems, pioneered by the Calzaferri group,,,,,, has been thoroughly investigated and the acquired knowledge played a seminal role, for example, in extending their scope to biomedical uses . Also importantly, dye‐zeolite L hybrids stimulated the quest of new host matrices for luminescent supramolecular systems: not only zeolite frameworks of diverse shape and composition,, but also mesoporous silicas/organosilicas,,,, 1D macrocycle channels,, and MOFs ,,…”
