Clays as a Host Matrix in the Synthesis of Organic Macrocycles
Chemistry – A European Journal, 2003 AbstractA new approach for the synthesis of amide macrocycles, based on the use of organo‐clay derivatives as controlling template, is proposed as an alternative to the rotaxane method. Dications of p‐xylylene diamine inserted in the clay interlayer space act as molding pillars around which neutral diamine molecules are erected via hydrogen bonding and

Direct Synthesis of Gold Nanoparticles in Polymer Matrix
Polymers, 2022 We report an original method for directly fabricating gold nanoparticles (Au NPs) in a polymer matrix using a thermal treatment technique and theoretically and experimentally investigate their plasmonic properties. The polymeric-metallic nanocomposite samples were first prepared by simply mixing SU-8 resist and Au salt with different concentrations ...
