And the article contained the following:

Herein, an efficient catalytic system for the direct synthesis of DPC from CO2, phenol, and carbon tetrachloride was developed by using a ZnCl2/copper triflate (Cu(OTf)2) composite catalyst. For the first time, high yield and high selectivity were achieved for DPC synthesis under mild conditions, even at atm. pressure. Carefully designed control experiments and DFT studies indicated that the synergistic activation of Cu(OTf)2 and its anion complex with ZnCl2 for phenol and CO2 led to a remarkably improved catalytic activity through a Lewis acid-assisted catalysis. This study not only provides a new strategy for efficient preparation of DPC but also offers an effective pathway for better CO2 utilization.

On September 2, 2020, Shen, Xiuqing; Du, Jiayuan; Sun, Jiaxin; Guo, Jia; Hu, Xinhua; Wang, Changchun published an article.Safety of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate) The title of the article was Transparent and UV Blocking Structural Colored Hydrogel for Contact Lenses. And the article contained the following:

Usually, materials with perfect structures possess excellent properties, but it is not always the case. Here, a new approach is reported to construct structural colored hydrogel films with excellent UV blocking performance for contact lenses. The theor. simulation predicts that with perfect periodic structures, the hydrogel films can strongly reflect incident light in a narrow visible wavelength range and thus exhibit extraordinarily brilliant colors. However, such hydrogel films cannot effectively block UV light. By slightly breaking the structural periodicity (quasi-periodic structure), strong diffuse scattering or pseudoabsorption of light can occur for all of the wavelengths shorter than a structural characteristic length, leading to perfect UV blocking. According to the theor. prediction, a structural colored hydrogel film with nearly periodic polystyrene sphere arrays in poly(hydroxyethyl methacrylate) hydrogel matrix is fabricated; this hydrogel film possesses brilliant colors and perfect UV blocking, and the core particle composition and size have been investigated in detail for the optimized properties of contact lenses. Meanwhile, the cell proliferation assay proves the cytocompatibility of the hydrogel for real application. Regarding its unique optical characteristics, the as-prepared structural colored hydrogel shows great promise in the fields of UV-protective equipment, medical device, soft robot, sensor, and so on. The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).Safety of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)
