| Research Abstract |
In this research, the author conceived the visualization of multi-stimuli on a material by utilizing aggregation-induced emission (AIE) property. An AIE dye moiety was introduced in the cross-linking point of elastomer derived from poly(dimethylsiloxane) (PDMS). The obtained elastomer exhibited photoluminescence due to the AIE function in dried state, while it was readily quenched when the elastomer was immersed in good solvent such as tetrahydrofuran (THF). Further, the emission became stronger with cooling the sample. These results suggested that the author successfully prepared a novel elastomer with multi-stimuli responsiveness.
