| Research Abstract |
For the purpose of development of a new technology to elevate product value of sulfur-containing materials and a new research field of sulfur chemistry, we investigated the synthesis and evaluation of novel sulfur-containing compounds. As a result, we developed high performance optical polymers such as 9,9-diarylfluorene- and 9,9'-spirobifluorene-containing polythioethers and polysulfones with high refractive index and low birefringence. In addition, we developed a recyclable cross-linked polymer based on a combination of dynamic covalent chemistry of aromatic disulfide bond and rotaxane chemistry, in which both the trunk polymer and the cross-linking agent change their positions without any apparent change in their chemical structures during cross-linking reaction.
