For optimizing the protocol of Zn-PMA metallogel, the experiments regarding the exploration of minimum critical gelation i.e., the MCG concentration level of Zn-PMA metallogel-forming chemical constituents like Zn(II) salt and pyromellitic acid were performed. MCG determination test was conducted by maintaining the fixed stoichiometric ratio of Zn(II) salt and pyromellitic acid as 1:1 with varying concentration levels increasing (i.e., Zn(II) acetate dihydrate = 0.1316 g, pyromellitic acid = 0.1524 g), 0.7 (i.e., Zn(II) acetate dihydrate = 0.1536 g, pyromellitic acid = 0.1779 g), 0.8 mM (i.e., Zn(II) acetate dihydrate = 0.1755 g, pyromellitic acid = 0.2033 g), respectively. protocol in DMF solvent is maintained throughout the entire investigations which were performed in different solvents (Figure ). For every cases of individual solvent, the metallogel-forming chemical constituents were mixed and then the possibility of gelformation from distinct set-up was checked through the inversion vial test. Experimental outcome clarified that stable metallogel has not been formed from any of these runs. Through several experiments it was ratified that DMF as the polar aprotic media is the exclusive gelimmobilized system to achieve the utmost stability of Zn-PMA metallogel.
