Instrument | Monowave 300 |
Description | In a G10 vial the iron oxide nanoparticles were suspended in THF. The self-assembly monolayer support is immersed and trimethylamine and the copper catalyst were added. The vial was sealed and subjected to microwave heating. |
Workup | No workup procedure was given in the papers. |
Comments | Reaction time was varied from 2 min to 1 h to investigate the assembly process.[1] After 1 h the maximum nanoparticle density on the substrate was obtained. Later the reaction was raised to 120 °C but still 1 h was required to achieve the same density. [2] The click chemistry under conventional reflux conditions requires 48 h for the same result. The two-dimensional nanostructure can be used as biosensors and for high density magnetic storage. |
