    Inverse-vulcanized polymeric sulfur has been prepared and utilized for solid-state dye sensitized solar cells. A power conversion efficiency of 1.5% was recorded with a short-circuit current of 4.1 mA cm-2 and an open-circuit voltage of 0.75 V under standard AM 1.5G illumination (1000 W m-2). The results in the present study qualify the new polymeric sulfur material as a future candidate as low-cost, hole-transport material for solid-state dye-sensitized solar cells.

    By a facile strategy, we obtained three pure regioisomers of multiaryl coronene bisimide (CBI) derivatives via IBr-mediated annelation and subsequent Suzuki coupling reactions with high yields. A series of aromatic groups with different electron properties were efficiently introduced to obtain functional CBI derivatives under mild conditions with good yields. Furthermore, the annelation mechanism as well as the optical and electrochemical properties of CBI derivatives were further investigated.

    The widely studied water oxidation catalyst [Ru-II(tpy)(L)(OH2)](2+) (tpy = 2,2': 6',2"-terpyridine, L = bpy = 2,2'-bipyridine or L = bpm = 2,2'-bipyrimidine) is still under scrutiny. Here we present a new suggestion for one of the key steps, results that could resolve conflicting interpretations of experimental results. Instead of the previously proposed Ru-V=O species, a proposed key species in water oxidation catalysis, we propose that the third oxidation of RuII could lead to a Ru-III N-oxide, via rapid water coordination followed by oxidation and concerted N-O bond formation.

    Molecular stacking dependent phosphorescence-fluorescence dual emission in a single luminophore for self-recoverable mechanoconversion of multicolor luminescence2017In: Chemical Communications, ISSN 1359-7345, E-ISSN 1364-548X, Vol. 53, no 18, p. 2661-2664Article in journal (Refereed)
    Abstract [en]

    A self-recoverable mechanoconversion of multicolor luminescence was observed by crystallization-induced self-assembly. Such a self-assembly led to the formation of nanorods with different molecular stacking modes, thus making the phosphorescence/fluorescence proportion alterable. Therefore, multicolor luminescence of the single luminophore can be achieved by a straightforward reversible mechanical stimulus.
