- Synthesis and spectral properties of unsymmetrical phthalocyanines from 3,6-dioctyloxyphthalonitrile and 3,4,5,6-Tetrachlorophthalonitrile
-
The random condensation of 3,6-dioctyloxyphthalonitrile (component A) with 3,4,5,6-tetrachlorophthalonitrile (component B) results in unsymmetrical phthalocyanines of A3B, ABAB, and AABB types. Their spectral properties were studied. Pleiades Publishing, Ltd., 2012.

- The synthesis of symmetrically octa-substituted phthalocyanines and their physical and photo-physical properties
-
A series of symmetrically substituted phthalocyanines have been synthesized from 3,6-dialkoxy-phthalonitrile and the corresponding metal salts. All of these complexes are extremely soluble in chloroform. Their melting points vary greatly with their different substituents. Their structures are confirmed by elemental analysis, 1H NMR, UV-VIS.

- Octa-alkoxy Phthalocyanine and Naphthalocyanine Derivatives: Dyes with Q-band Absorption in the Far Red or Near Infrared
-
The lithium alkoxide-catalysed cyclic tetramerisation of various 3,6-dialkoxy-4,5-dichlorophthalonitriles, 1,4-dialkoxynaphthalene-2,3-dicarbonitriles and 3,6-dialkoxyphthalonitriles to give the corresponding metal-free octa-alkoxyoctachlorophthalocyanines, octa-alkoxynaphthalocyanines and octa-alkoxyphthalocyanines is described.An unexpected trans-alkoxylation reaction occurs during the cyclisation of the first two series of precursors.Metal-free phthalocyanines and naphthalocyanines have been converted into derivatives containing various metal ions.Compounds show Q-band absorption in the region 739-862 nm in toluene solution.The fluorescence spectra of selected examples are reported.The solubility of some of the compounds has been measured in a formulation of liquid crystal materials.
