Dynamic covalent polymers—dynamers—are adaptive materials that offer timely variant adaptive macroscopic organization across extended scales. In the current study, imine exchange reactions and fluorescence transfer can occur at the interfaces between vari

The synthesis of a series of ruthenium(II) based anion sensors of the type [Ru(η6-C6H4MeCHMe2)-Cl(L) 2][BF4] (2) is reported in which ligand L represents a series of substituted pyridinylmethyl-amine derivatives. The carbazole based ligand L3 exhibits a fluorescent intraligand charge-transfer (ILCT) state that is quenched by ligand-to-metal charge transfer (LMCT) upon coordination to ruthenium in the 1:1 complex [Ru(η6-C 6H4MeCHMe2)Cl2(L3)] (1c). The 1:2 complex 2c is fluorescent, however, and acts as a fluorescent anion sensor because of the mixing of an anion-dependent charge-transfer component into the excited state. The 1:2 complexes of type 2 all exhibit interesting low symmetry 1H NMR spectra that also are a useful handle on anion complexation. The electronic structures of L3, 1c and 2c have been probed by time-dependent DFT calculations.
