| Abstract: | The variation of the pyroelectric response (temperature-dependent electric polarisation) of alternate-layer acid/amine films of calix(8)arenes differs according to the structure of their pendant hydrophobic chains. t-Butyl calix(8)arenes exhibit larger pyroelectric coefficients than the t-octyl analogues. A coefficient of 15 μC m−2 K−1 has been obtained for a 13-alternate-layer sample of acid- and amine-substituted t-butyl calix(8)arene. |
