Graphical Abstract

Polyfunctional gels: Thermoreversible switchable gels with tunable magnetic, optical, and rheological properties are obtained from a modified spin-crossover polymeric precursor and alkane solvents (see picture). The iron triazole polymer which acts as the gelator, undergoes a spin crossover that is accompanied by a change in the color of the gel. The transfer of spin-crossover properties from solid materials into gels offers a route to new applications.

12Note that the pure ligand 4-octadecyl-1,2,4-triazole does not gelify alkane solvents, while gels are also obtained starting from SC solids having other lengths of alkyl substituents (C₁₃ and C₁₆) on the triazole rings.

15When the triazole ligand is in a local C_2v symmetry (case of a 1,2-bridging coordination mode), the intensity of ring torsion vibration modes is weak compared to their intensities in a non-C_2v case, as for example, in the pure 1H-1,2,4-triazole. In our case in the gel spectra, these vibration bands at approximately 670 cm⁻¹ are very weak confirming the local C_2v symmetry.
