Resumo

An abrupt lengthening (from 295 to 684 μs) of the luminescence decay time of Tb3+ ions in a solution of a terbium(III) complex with tetra-1,3-diketone calix[4]arene in the region of the solution crystallization temperature (212 K) was found. This fact indicates a significant sensitivity of the complex to the structure of the local environment, which can be used both for spectroscopic purposes and for remote monitoring of the phase state of the medium.
