A breath of fresh air is sufficient for the eightfold S-monooxygenation of an interpenetrated double cage based on eight phenothiazine ligands and four square-planar-coordinated PdII cations. Besides these two cages, which were both characterized by X-ray crystallography, an eightfold S-dioxygenated double-cage was obtained under harsher oxidation conditions.

Starting from N-hexylphenothiazine, a versatile construction kit of brominated and borylated phenothiazines can be easily prepared by a sequence of bromination, bromo-lithium exchange/borylation, and Suzuki coupling. Subsequent Suzuki arylation of the building blocks gives soluble, monodisperse, and structurally well defined oligophenothiazines in good yields. The molecular weights at the peak maximum (Mp), obtained by GPC (gel permeation chromatography), and the actual molecular weights of the oligomer series, obtained by mass spectrometry, show excellent correlation. A QM/MM conformational analysis for the complete series reveals that the obvious butterfly-shaped phenothiazine structure multiplies and significantly reduces the hydrodynamic volume of the oligomers. The electronic properties (absorption and emission spectroscopy and cyclic voltammetry) give reasonable correlations with the chain length. With regard to the emission maxima, the effective conjugation length is already reached with the hexamer. Oligophenothiazines are highly fluorescent, with high fluorescence quantum yields, and are simultaneously highly electroactive, with low oxidation potentials.

In this work, we designed and synthesized two new phenothiazine dyes CBPTZ-BTD1 and CBPTZ-BTD2, which employed the electron-accepting moiety of benzothiadiazole (BTD). The structural difference between the two new dyes is due to the presence of an ethynyl unit between BTD and the benzoic acid. With respect to its congener CBPTZ-BTD1, CBPTZ-BTD2 with the insertion of ethynyl group shows a more coplanar molecular skeleton, which endows CBPTZ-BTD2 with a higher dye loading and a strengthened ICT effect, resulting in a red-shifted ICT absorption with a higher molar extinction coefficient. Besides, CBPTZ-BTD2 has a longer electron lifetime in comparation with CBPTZ-BTD1 without the linear ethynyl unit, as reveled by OCVD and EIS measurements. Therefore, CBPTZ-BTD2 exhibits a better photovoltaic performance with an enhanced JSC of 14.04 mA cm?2 and VOC of 0.82 V, leading to an improved PCE of 7.33 %.
