Novel dibenzothiophene chromophores with peripheral barbituric acceptors

A series of novel chromophores based on central 2,8-disubstituted dibenzothiophene (DBT) or dibenzothiophene-S,S-dioxide (DBTO) has been designed and prepared. The interconnection of DBT(O) central scaffold with two peripheral barbituric acceptors via various π-spacer allowed significant property tuning of target chromophores. Four new final chromophores and six DBT(O)-intermediates have been successfully synthesized and fully characterized. Experimental and calculated data showed that the fundamental properties are affected by the chromophore A-π-D-π-A or A-π-A-π-A arrangement (DBT vs. DBTO) and the π-linker (ethenylene vs. ethynylene). Thorough structure-property relationships have been elucidated and discussed in detail.

Ruthenium complex luminescent material containing dibenzothiophene sulfone group and use thereof

The invention discloses a ruthenium complex luminescent material containing a dibenzothiophene sulfone group and a use thereof. The ruthenium complex takes a dibenzothiophene sulfone pyridine derivative as a ring metal ligand and takes picolinic acid as an auxiliary ligand; and a hole transport unit is introduced on the ring metal ligand, to balance the electron and hole transport capability of the ruthenium complex. The ruthenium complex is doped in PVK and PBD to form a light-emitting layer, and a high-efficiency polymer yellow light device is obtained; the ruthenium complex and FIrPic are mixed as a dopant, are doped into polymer PVK and OXD-7 to form a light-emitting layer. The complementary color principle is utilized to obtain an efficient polymer white light device, and the application of an OLED in flat panel display and white light lighting is promoted.

Blue oligomer based on dibenzothiophene-S,S-dioxide unit and preparation method and application of blue oligomer

The invention discloses a blue oligomer based on a dibenzothiophene-S,S-dioxide unit and a preparation method and application of the blue oligomer. The blue oligomer is mainly characterized by comprising a fluorene structure unit and the dibenzothiophene-S,S-dioxide structure unit. The preparation method mainly comprises the step of preparation of the blue oligomer based on the dibenzothiophene-S,S-dioxide unit. Due to the fact that the electroluminescence efficiency and the spectral stability are improved by introducing the dibenzothiophene-S,S-dioxide structure unit into the oligomer, the novel oligomer blue-light emitting material is obtained. According to the obtained blue oligomer based on the dibenzothiophene-S,S-dioxide unit, an electroluminescence device prepared through film formation of a solution processing method is high in efficiency, good in spectral stability and suitable for being adopted as a light-emitting layer of a light-emitting diode and a flat-panel displayer.
