A series of [C60/C70] fullerene derivatives containing different spirobifluorene and tri-Ph imidazole were synthesized and confirmed by IR, 1H NMR, 13C NMR, MALDI-TOF-MS. Their optical limiting properties were investigated by nanosecond and femtosecond laser systems. Results showed that fullerene derivatives exhibited high optical limiting properties. Lower OL thresholds of 13.7, 14.9, 15.3, 23.3, and 24.0 J/cm2 were observed for C70-SBF, C60-TPI, C60-SBF, C60-FSBF, and C60-BTPI resp. with the linear transmittance of 75%, which implied that these optical limiting properties increased with the degree of conjugation and electron-donating or electron-accepting abilities of donors or acceptors in donor-acceptor (D-A) structures. The strong D and A with large conjugation is an effective way to enhance OL properties. This study involved multiple reactions and reactants, such as 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4Quality Control of 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate).
1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate (cas: 478935-29-4) belongs to imidazole derivatives. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole has become an important synthon in the development of new drugs. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Quality Control of 1-Hexyl-3-methyl-1H-imidazol-3-ium hydrogensulfate
