Abstract: Photophysical properties and photodynamic activity for a series of cyanoarylporphyrazine pigments have been analyzed depending on the nature of the substituents and their position in the aromatic ring. Replacement of the fluorine atom in the par

A new approach for the synthesis of tetrasubstituted/functionalized NH-pyrroles from gem-diactivated acrylonitriles and TMSCN has been developed. The strategy utilizes the generation of vic-dinitrile via Michael addition and cyanide-mediated nitrile-to-nitrile cyclocondensation, which proceed in tandem guided by manifold roles of CN . An extended application to the production of fused pyrrole has also been realized.

Peripheral substitution with electron-donating (push) and electron-withdrawing (pull) substituents caused a sizeable red-shift of the Q band absorption and fluorescence of subporphyrazine, and the red-shift was controlled by the push substituents. Control
