•2D nanosheet structures are formed in sulfamethoxypyridazine/β-CD inclusion complex.•Self assembled nanorods are formed in sulfamethoxypyridazine/α-CD inclusion complex.•Intermolecular hydrogen bonding play a vital role in the supramolecular self assembling process.•The size of the CD determined the shape of the supramolecular architecture.
A 2D nanosheet was fabricated through the supramolecular self assembly of sulfamethoxypyridazine (SMP) and β-cyclodextrin (β-CD) inclusion complexes. HRTEM image exhibited 2D nanosheet morphology with a length of 1200 mm and the sheet thickness of 60 mm. It is noted that the nanosheet did not form a single layer aggregation but a bulk aggregation of SMP/β-CD inclusion complex. The formation of this multilayer 2D nanosheet based on the self assembly of SMP/β-CD inclusion complexes is proposed by the topological transformation as well as molecular modeling calculations. But, nanorods are formed in SMP/α-CD inclusion complex indicated that the nature of the CD determined the shape of the self assembled supramolecular architecture. The formation of nanomaterial was characterized by using FT-IR, DSC, PXRD, 1H NMR, absorption, fluorescence and lifetime measurements.
