A novel bipolar compound triphenylamine-dibenzothiophene S,S-dioxide (TPAFSO) based on a dibenzothiophene-S,S-dioxide (DBTO) moiety and a triphenylamine (TPA) unit, in which the TPA unit is linked at its 4-position to the DBTO group at its 3,7-position, i

Several well-defined donor-acceptor (D-A) dibenzothiophene-S,S-dioxide (SO) derivatives possessing aggregation-induced emission (AIE) behaviour decorated by tetraphenylethene (TPE) and triphenylamine (TPA) were synthesized and characterized. The photophys

Four triphenylamine or carbazole-based highly emissive solid fluorophores (The maximum quantum yield of 42.43%) of dibenzothiophene sulfones have been successfully prepared and characterized. The solid-state emission behaviors and mechanical stimulus-responsive luminescence characteristics of all these donor-acceptor-donor (D-A-D) type or donor-π-acceptor-π-donor (D-π-A-π-D) type compounds 1–4 were investigated. Interestingly, these fluorophores 1–4 exhibited various solid-state fluorescent colors involving blue (CIE color coordinates of (0.15, 0.09)), blue-green (CIE color coordinates of (0.17, 0.43)), yellow (CIE color coordinates of (0.41, 0.56)) and brown-yellow (CIE color coordinates of (0.50, 0.50)). Furthermore, these dyes 1–4 also exhibited different mechanofluorochromic behaviors. More specifically, luminogens 1–3 showed bathochromic mechanofluorochromic phenomena. However, luminogen 4 showed distinct-different hypsochromic mechanofluorochromic phenomenon. All these observed mechanochromic emission conversions could be repeated for many cycles. Single-crystal X-ray diffraction and powder X-ray diffraction experiments demonstrated that the mechanofluorochromic behaviors of 1–4 were related to the morphology transformation from crystalline state to amorphous state.

Fluorescent oligomers where the backbone of dibenzothiophene-S,S-dioxide acts as the acceptor and side chains of aryl methoxy, fluorene, and arylamine act as the donors have been effectively synthesized by the palladium-catalyzed Suzuki coupling reactions, and the photo-physical properties of the compounds were investigated. From the single-crystal XRD patterns the compounds reveal a twisted conformation with an intramolecular structure and show close relationship between intramolecular or intermolecular charge transfer and their photo-physical properties. These patterns provide more comprehensive information, which is unattainable from 1H NMR and 2D-COSY spectra. The emission spectrum in the range of 450-510 nm can be finely tuned by systematically altering the position of substitution on the donor units of side chains connected with the backbone acceptor. The fabricated devices displayed a sky blue to deep green in terms of color and performed the CIE (x,y) coordinates with values of (0.18-0.21, 0.25-0.46), respectively.
