A series of calix[4]arene-based fluorescent chemosensors in cone and 1,3-alternate conformations have been synthesised incorporating ethylene glycol units as binding sites and coumarin as fluorescent probe. These compounds have been designed with variation in substituents, conformations of the calixarene unit and steric crowding. The open chain ethylene glycol moieties are flexible so that they can
