title: [Spectroscopic study on the performance of 1,3-thiacalix [4] rhodamine ethyldiamine amide derivatives to Fe3+ ion].
abstract: The two di-substituted rhodamine-based thiacalix[4]arene ethyldiamine amide derivative were synthesized from thiacalixrene and rhodamine B ethyldiamine by acylation. Under the experimental conditions, the derivatives and Fe3+ are able to form a 1:1 complex. The formation of complex leaded to the moiety opening of rhodamine, and showed the good fluorescent and colorimetric performance. Among them, the selectivity of 1, 3-thiacalix[4] rhodamine ethylenediamine amide-2, 4-ester to Fe3+ is higher than 1,3-thiacalix [4] rhodamine ethylenediamine amide-2,4-acid. The analysis feature of the probes response to Fe3+ was studied by spectroscopy, and synthetic samples were determinec.
