摘要
A new tetra hydroxyl methoxy substituted calix[4]pyrrole (HMCP) has been synthesized and found to form stable complex with F-ions and Cu+2 ions. The red-shift in absorption band of HMCP was observed due to the presence of both cation (Cu+2) and anion (F-). These results displayed that formation of the complex is mainly attributed to the charge transfer interactions between HMCP with electron deficient pyrrole rings and the electron-rich guest ions. Molecular dynamics simulation predicts intermolecular H bonds and van der Waals types of interaction for the complex formation of HMCP-Cu+2 and HMCP-F.
