Herein, we have implemented an intimate grinding-mixing protocol (GMP) for the synthesis of a new hydrogelator from citrazinic acid and melamine. Ground mixture upon sonication, just for few second, in a suitable solvent/mixed-solvent system finally results in a gel matrix.Citrazinic acid, is decorated with ureidopyrimidone functionality and melamine is enriched with amino-pyridine functionality. Therefore, the necessary non-covalent interactions (like hydrogen bonding and π-π stacking) become a part-and-parcel, bringing a nanofibrous gel material in existence. A thorough and complete solvent dependent gelation investigation suggests that water must be present as the sole solvent or one of the members of other mixedsolvent system to successfully result in gel formation. The gel shows entangled network morphology. Different micro-analytical studies (FTIR, Powder XRD, FESEM, TEM, Rheology etc.) have been conducted for complete characterizations of the gel sample. The gel also exhibits its stimuli responsive behaviour towards different interfering chemical parameters like pH, selective anions etc. Again, it is worth mentioning that here GMP plays a key role to strongly initiate and improvise solid state self-assembly. Different non-covalent interactions procure the suitable hydrogen-bonded motif which presumably propagates upon activation in solution phase after mild sonication favouring spontaneous formation of fibrous architectures. It was also noticed that without grinding, the solid state interactions are jeopardized and only partial gel structure prevails. Finally the available porosity in the gel framework and the enriched π-electron density within, make the gel a suitable host for adsorption of guest molecules. This information provoked us to study the reversible adsorption-desorption equilibrium of molecular iodine within the dried-gel matrix. The guest, iodine entrapment into the host occurs both from the solution and also from gas phase iodine.The complete analysis suggests that our material presents a high storage capacity of this halogen species. Therefore the study prescribes that the synthesized hydrogel material could be a suitable candidate for application in synthetic organic chemistry and would find an avenue to solve other environmental issues also.Melamine and citrazinic acid, upon solid state grinding, produced a two-component gelator
