Association constants have been determined for pyrene as a guest molecule for 9 water-soluble calix[n]arenes (n = 4, 6, and 8) bearing sulphonate groups on the 'upper rim' (1) or on the 'lower rim' (2). The results have established that calixarene (1) has a strong but non-selective binding site whereas calixarene (2) has a relatively weak but selective binding site.
