We are presenting a new derivative of the fluorubine family which exhibits highly fluorescent activity. 5-Phenyl-dihydro[5,6,7,12,13,14]-hexaazapentacene was synthesized via two subsequent cyclization reactions starting from com. available starting materials. Its properties were studied intensively via UV-vis and fluorescence spectroscopy, as well as cyclic voltammetry and quantum chem. calculations Furthermore, we found a strong pH-sensitivity, which influences the photo- and electrochem. properties heavily. Thereby, it is possible to tune its properties from an electron-rich donor to a highly electron-deficient acceptor material.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called The synthesis of metal-free octaazaphthalocyanine derivatives containing bulky phenoxy substituents to prevent self-association, published in 2007-10-08, which mentions a compound: 56413-95-7, mainly applied to octaazaphthalocyanine phenoxy substituted preparation; pyrazinedicarbonitrile cyclocondensation, Application In Synthesis of 5,6-Dichloropyrazine-2,3-dicarbonitrile.

Octaazaphthalocyanines with eight phenoxy groups in the peripheral sites are prepared for the first time using the simple synthetic procedure of heating their pyrazine-2,3-dicarbonitrile precursor in quinoline. This process avoids transetherification, which has hindered previous attempts at preparing metal-free octaazaphthalocyanines. Metal-containing derivatives were also prepared by adding the appropriate metal salt to the reaction mixture Bulky iso-Pr or Ph groups at the 2,6-positions of the phenoxy substituents prevent self-association of the octaazaphthalocyanine cores even in the solid state.
