DOI: 10.1002/adfm.201703509
Abstract: White light-emitting phenothiazine-poly(dimethylsiloxane) (PTZ–PDMS) composites are formed by a photooxidation reaction. The oxidized PTZ species, i.e., PTZ cation radicals and dication species, are created by electron transfer from the PTZ molecules to PDMS under UV… read more here.
