SYNTHESIS OF FULLEROPYRROLIDINE PYRIDINIUM SALTS BY FACILE ANION EXCHANGE AND THEIR SOLUBILITY
CHRISTOPHER M. TOLLAN,JOSE A. POMPOSO,DAVID MECERREYES 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2009 NANO Vol.4 No.5
Several ionic fullerene salts have been prepared based on a fulleropyrrolidine pyridinium cation and four different anions. The initial ionic fullerene can be easily prepared by quaternization of a pyridine-appended fulleropyrrolidine derivative in high yield. Anion exchange is a simple procedure giving several different salts of varying polarity. In addition to their characterization, the quantitative solubility of these salts has been studied in seven different solvents, including an imidazolium ionic liquid.
NEW AMINE FUNCTIONAL IONIC LIQUID AS BUILDING BLOCK IN NANOTECHNOLOGY
IBON ODRIOZOLA,REBECA MARCILLA,DAVID MECERREYES,JOSE A. POMPOSO,JAVIER RODRIGUEZ 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2007 NANO Vol.2 No.3
In this communication, we report the synthesis of an amino-functionalized ionic liquid (AFIL) and its application as building block in the construction of new functional nanomaterials. This AFIL has been used as surfactant in the synthesis of gold nanoparticles (Au NPs) and in the development of functional CNTs/IL hybrid nanomaterials by mixing the AFIL with multi-walled carbon nanotubes (MWCNTs). The presence of an amine group in the ionic liquid provides to the resultant nanomaterial with new opportunities in several applications in the nanobio field.
