Exploring of the property of epoxy resins based on diselenide and disulfide dynamic linkers

Frontiers in Chemistry, 2022
Over the last decade, there has been a lot of interest in incorporating dynamic covalent bonds (DCBs) into epoxy resins. Because diselenide and disulfide bonds have similar properties, they are frequently used as DCBs in self-healing epoxy networks.

Crystal structures of 4,4′-(disulfane-1,2-diyl)bis(5-methyl-2H-1,3-dithiol-2-one) and 4,4′-(diselanane-1,2-diyl)bis(5-methyl-2H-1,3-dithiol-2-one)

Acta Crystallographica Section E: Crystallographic Communications, 2018
The two title compounds, C8H6O2S6 and C8H6O2S4Se2, are isotypic with very similar cell parameters. The complete molecules constitute the asymmetric units, despite being chemically perfectly symmetric.
