Facile synthesis of dicyanovinyl-di(meso-aryl)dipyrromethenes via a dipyrromethene-DDQ adduct.
The dicyano-substituted vinyl dipyrromethene and compound are near-planar and were prepared from a simple meso-aryl dipyrromethane via the DDQ adduct ; the unique structures of , and were confirmed by X-ray diffraction analysis.
