The temporal control (ON/OFF/ON) of the fluorescence of a dichloromethane/acetonitrile 1 : 1 solution of calixarene 3 decorated with two pyrenyl moieties at the upper rim is attained by the addition of CCl3CO2H used as a convenient chemical fuel.

In this work, we report that 2-cyano-2-phenylpropanoic acid and its p-Cl, p-CH(3) and p-OCH(3) derivatives can be used as chemical fuels to control the geometry of the calix[4]arene scaffold in its cone conformation. It is shown that, under the actio

A calix[4]arene scaffold, blocked in the cone conformation and decorated at the upper rim with two acylguanidine units, effectively catalyzes the cleavage of phosphodiester bonds of HPNP and BNPP under neutral pH conditions. The catalyst performance

Calixarenes have been widely employed as building blocks in the design of supramolecular catalysts. As shown in the examples reported here, the molecular cavity itself can be involved as a recognition unit for inclusion of the substrate or of part st
