A series of phenothiazinyl- and 4-diethylaminophenyl-substituted diethylenes were synthesized and characterised; their thermal, optical and photoelectrical properties were investigated. TGA showed that the compounds display high thermal stability, achieving 5% mass loss at temperatures up to 385 °C; DSC revealed that many of the compounds exhibited glass transition temperatures ranging from 20 to 124 °C. Dilute solutions of the diethylenes exhibited fluorescence emission in the green-blue region with an efficiency reaching 99%. Electron photoemission spectrometry and time of flight revealed ionization potentials of 5.34–5.52 eV; the room temperature hole drift mobility of one of the compounds molecularly doped in bisphenol Z polycarbonate exceeded 10−5 cm2/Vs under a high electric field.
