Two benzoporphyrin derivatives substituted with long side chains at the bay positions have been synthesized through a facile route. They were confirmed to show two separate columnar phases upon cooling, i.e., a hexagonal columnar phase and a rectangular columnar phase. In particular, the temperature dependence of the electronic spectra revealed that the Q-band split into two peaks, indicating the existence of typical herringbone-type dimers. Moreover, their photoconductive properties were studied by steady-state and transient photocurrent measurements. It was found that both benzoporphyrins exhibited very fast hole mobility over 0.1 cm2 V-1 s-1 in both columnar phases and a high charge carrier generation efficiency up to 2%, demonstrating that they are potential p-type organic semiconductors for photovoltaic devices.

The paper reviews a selection of synthetic pathways that provide access to 3,6-disubstituted phthalonitriles, precursors for the synthesis of 1,4,8,11,15,18,22,25-octasubstituted phthalocyanine derivatives. Early routes using Diels-Alder reactions for the

A number of novel carbonyl(1,4,8,11,15,18,22,25-octaalkylphthalocyaninato)- ruthenium(II) complexes were prepared by metal insertion with Ru 3(CO)12. The new compounds have been characterized by 1H NMR, 13C NMR, IR, UV-vis and mass spectroscopy. This study demonstrated that this type of complexes and specifically carbonyl(1,4,8,11,15,18,22,25-octahexylphthalo-cyaninato)ruthenium(II) and carbonyl[1,4,8,11,15,18,22,25-octa(2-cyclohexylethyl)phthalocyaninato] -ruthenium(II), exhibit high catalytic activity and stability in the epoxidation of stilbenes with 2,6-dichloropyridine N-oxide as oxidant.
Synthesis and Characterisation of some 1,4,8,11,15,18,22,25-Octa-alkyl- and 1,4,8,11,15,18-Hexa-alkyl-22,25-bis(carboxypropyl)phthalocyanines

A series of 3,6-dialkylphthalonitriles and 3,6-bis(4,4,4-trimethoxybutyl)phthalonitrile have been prepared via Diels-Alder reactions of 2,5-disubstituted furans or thiophene 1,1-dioxides with fumaronitrile.The phthalonitriles were converted into the title phthalocyanines as metal-free and copper(II) derivatives.The macrocycles were characterised using 1H NMR and optical spectroscopy, and fastatom bombardment spectrometry.Certain examples exhibit discotic liquid crystal behaviour.
