Polarimetry was used to investigate the binding abilities of a chiral calix[4]resorcinarene derivative, bearing L-proline subunits, towards a set of suitably selected organic guests. The simultaneous formation of 1:1 and 2:1 host–guest inclusion complexes was observed in several cases, depending on both the

During the last decades calix[n]arenes and calix[n]resorcinarenes (CAs) have emerged as versatile supramolecular host systems for various applications [1][2][3][4][5], spanning from sensors
thermodynamic aspects of the binding phaenomena involving CAs, as well as at verifying the possibility to extend the use of polarimetry as an investigation tool to these systems, in the present work we studied the binding abilities of an easily accessible L-proline-derivatized calix[4]resorcinarene, namely
