WebLuo, C. Zhao, J. Xie, H.-f. Lu, Synthesis, 2016, 48, 3696-3700. A dioxygenation of alkenes using molecular oxygen and a simple, readily prepared hydroxamic acid derivative in th presence of a radical initiator offers an alternative to common dioxygenation processes catalyzed by precious transition metals. WebThe absorption, fluorescence, and electrochemical properties were also studied. Photoluminescence of these chromophores ranges from 900 to 1600 nm and their band gaps are between 1.19 and 0.56 eV. Replacing the sulfur by selenium can lead to a red shift for emission and reduce the band gaps further.
