Photoluminescent materials play an essential part in the application of polymer systems. However, intrinsic polymer systems have rarely been intuitively interpreted based on photoluminescent regulation. A novel photoluminescent mechanism called vibration-induced emission (VIE) has recently garnered considerable attention due to its multicolor fluorescence from a single mol. entity. Based on the unique fluorescent properties of VIE mols., we have doped 9,14-diphenyl-9,14-dihydrodibenzo[a, c]-phenazine (DPAC) and its derivative DPAC11-carbonitrile in two stretchable polymers, poly (ε-caprolactone) and ethylene vinyl acetate (EVA) copolymer, to explore the important relationship between luminophores and polymer systems. This research focuses on the multicolor photoluminescence of the blend films that result from stretching exertions and temperature responses. The successive conformational alterations of VIE mols. endow continuous photoluminescent changes. Meanwhile, the multicolor variations also provide specific visual evidence regarding the amplified tensile stresses and microstructural changes in the polymer. This demonstration therefore provides advantageous insight into the development of functional optical materials. In the experiment, the researchers used many compounds, for example, Copper(II) trifluoromethanesulfonate (cas: 34946-82-2Recommanded Product: Copper(II) trifluoromethanesulfonate).
Copper(II) trifluoromethanesulfonate (cas: 34946-82-2) belongs to copper catalysts. The applications of Copper-based nanoparticles have received great attention due to the earth-abundant, inexpensive and low toxicity. These ligands enable the reaction promoted in mild condition. The reaction scope has also been greatly expanded, rendering this copper-based cross-coupling attractive for both academia and industry. Recommanded Product: Copper(II) trifluoromethanesulfonate
