Design of OsII‐based Sensitizers for Dye‐Sensitized Solar Cells: Influence of Heterocyclic Ancillaries

-based coun-terparts, in which the azolate (both pyrazolate and triazolate)fragments are located at the mutual trans-positions. The basicproperties were extensively probed by using spectroscopicand electrochemical methods as well as time-dependent densi-ty functional theory (TD-DFT) calculations. Fabrication of dye-sensitized solar cells (DSCs) was then attempted by using theI /I
