FT-IR spectroscopic investigation (Figure ) was done with the xerogel sample of Zn-PMA metallogel for identifying the impact of metallogel-forming chemical ingredients such as Zn(II) acetate dihydrate and pyromellitic acid toward the successful formation of stable metallogel of Zn(II) (i.e., Zn-PMA metallogel). FT-IR study (Figure ) also supports to unveil the role of non-covalent supramolecular interactions responsible to achieve the stable metallogel in polar aprotic solvent media like DMF. Along with the xerogel sample of Zn-PMA metallogel, the FT-IR patterns of Zn(II) acetate dihydrate and pyromellitic acid were also collected for getting the utmost comparative idea (Figure ). The experimental data revealed significant shifts in stretching frequencies, suggesting supramolecular interactions between the chemical components that play critical role in metallogel-formation. In the spectrum of the xerogel-form of metallogel, relevant peaks observed at 3567-3169 cm -1 for stretching vibration of O-H, 1594 cm -1 for the stretching vibration of C=O, 1550 cm -1 for asymmetric stretching vibration of COO, 1399 cm -1 for symmetric stretching vibration of COO, 1145 cm -1 for stretching vibration of C-H bond, 629 cm -1 for bending vibration of the were significantly shifted to lower wavenumber (cm -1 ) with respect to the standard experimental values of metallogel-constructing individual pure-ingredients like pyromellitic acid [3567-3169 cm -1 for ν(OH), 1594 cm -1 for ν(CO), 1550 cm -1 for ν a (COO), 1399 cm -1 for ν s (COO), 1145 cm -1 for ν(C-H), 629 cm -1 for ν b (CO)] and Zn(II) acetate dehydrate (Figure ). Besides, the aspect of Zn(II)-metallogel-creating most possible arrangements of Zn(II) acetate metal salt with pyromellitic acid as the low moleculer weight gelator was evolved by performing the ESI-Mass analyses (Please see Figure in Supplementary material). For getting stable Zn-PMA metallogel, the network of 3D soft-scaffold was achieved by employing one unit of Zn(II) acetate metal source connected with two units of pyromellitic acid form either sides with help of non-covalent type supramolecular interactions and this might be considered as the iterating structural-moiety which might be critically accountable for trapping suitable polar aprotic solvent of DMF in the supramolecular Zn-PMA metallogel.
