A series of new room-temperature ionic liquids (RTILs) based on biodegradable pyridinium carboxamide cation and conformationally flexible NTf2 anion have been synthesized. The variation of thermo-phys. properties of these RTILs with alkyl chain length size has been studied and compared with corresponding parental pyridinium NTf2 ILs. A drastic change in thermophys. properties has been noted on the introduction of the amide functionality on pyridinium cation moiety. The crucial role of amide functionality is also important concerning biodegradability as it acts as an active site for an enzymic attack, helpful toward biodegradation Besides, the dependence of thermal and phys. properties on alkyl chain length is also noteworthy. A detailed DFT based theor. studies substantiate the exptl. observation of chain length dependence m.p. variation and successfully correlated that with stabilization energy. Conformational dynamics of NTf2 anion (between transoid and cisoid) has been elucidated by Raman spectroscopic studies. Interestingly, the data demonstrate that the conformation of NTf2 anion depends on the chain length of the cation, clearly indicating anionic interaction with the hydrophobic region of the cation. This information is crucial as it vindicates the fact that multiple weak interaction do exist in ILs making it a complex nanostructured system composed of ions.
