Abstract
The photo-physical and electroluminescent properties of five PPV-type conjugated polymers containing phenothiazine and phenothiazine-5-oxide moieties were studied by UV–vis, PL and EL methods. The polymers showed PL maxima in the range 546-553 nm in solution and is 574–589 nm in solid. Red shifts in PL of P2, P3 and P4 were observed and can be explained by intra-molecular charge transfer effect. Yellowish-green light ranging from 568 to 576 nm with luminance up to 200 cd/m2 was observed for the single layer device with the configuration of ITO/Polymer/Ca/Al.
