To prepare stable nanohybrids of controlled size and shape consisting of a noble metal core decorated with polydiacetylenes (PDAs) was the aim of our work. Due to the combination of the outstanding linear and nonlinear optical properties of the polydiacetylenic chains with the electromagnetic field-enhancing capability of metal nanostructures,...

This paper reports on the fabrication of self-assembled monolayers containing disulfide-functionalized diacetylenes. To this purpose, two diacetylene derivatives were synthesized:  the novel 14-(9H-9-carbazolyl)tetradeca-10,12-diyn-1-yl disulfide (CDS9) and the henicosa-10,12-diyn-1-yl disulfide (DS9). Both monomers were employed to prepare...

Stable chitosan-protected noble metal nanocages of relatively small size (~ 50 nm) were successfully synthesized by the galvanic replacement reaction between the corresponding silver nanoparticles and HAuCl4 in aqueous suspension. A broad surface plasmon band peaked around 700 nm and extended to the near-infrared was observed by properly...
