The present invention relates to a compound for an organic optoelectronic device, represented by Chemical Formula 1; a composition for an organic optoelectronic device, including same; an organic optoelectronic device; and a display device. The description of Chemical Formula 1 is the same as that defined in the specification.
Under Pd(II)/CuI cocatalysis, o-diarylphosphinophenylalkynes cyclize in boiling toluene via C–P bond cleavage and arylphosphination of the C≡C bond. This protocol provides an unprecedented atom- and step-efficient access to optoelectronically and biologically interesting benzophospholes.
Electron‐donating aryl groups were attached to electron‐accepting benzophosphole skeletons. Among several derivatives thus prepared, one benzophospholeoxide was particularly interesting, as it retained high fluorescence quantum yields even in polar and protic solvents. This phosphole‐based compound exhibited a drastic color change of its fluorescence spectrum as a function of the solvent polarity
