Polyphosphazene-based electrolytes containing different iodide salts were studied as components of dyesensitized solar cells (DSSCs). Electrolytes based on hexa[methoxyethoxyethoxycyclotriphosphazene] (MEE trimer) with dissolved LiI, NaI, NH4I, and 1-methyl-3-propylimidazolium (PMII) and I2 were examined by ac conductivity and steady-state voltammetry. These measurements gave the individual con...
The Staudinger reactions of substituted phosphanes and azides have been investigated by using density functional theory. Four different initial reaction mechanisms have been found. All systems studied go through a cis-transition state rather than a trans-transition state or a one-step transition state. The one-step pathway of the phosphorus atom attacking the substituted nitrogen atom is always...
