Novel meso-aryl substituted expanded porphyrins comprising of alternate arrangement of more than six of pyrrole units bridged by a methine group whose hydrogen is substituted with Ar-group; and their synthetic method. Ar-group is either a 2,6-substituted phenyl group which can possess a substituent at the other 3, 4, and 5 positions, or 9-anthryl group which can possess a substituent at the other positions of the anthracence, or a cyclohexyl group which can possess a substituent at the other positions of the cyclohexyl group. The substituents at the 2 and 6 positions mentioned above can be selected independently from halogen atom or lower alkyl group of carbon number 1 to 4, substituents at 3-5 positions, 9-anthryl group and cyclohexyl group can be selected independently from the group consisting of substituted or non-substituted alkyl of carbon number 5 or 6, substituted or non-substituted aryl group, besides above mentioned substituents at 2 and 6 positions. Each Ar-group can be different.
La présente invention concerne de nouvelles porphyrines expansées dans lesquelles au moins six noyaux pyrrole et des groupes méthine substitués Ar sont liés de manière alternée aux positions alpha des noyaux pour former un macrocycle. Cette invention concerne également un procédé permettant la préparation de ces porphyrines. Selon l'invention: Ar est phényle 2,6-disubstitué qui peut également comporter des substituants aux positions 3 à 5, 9-anthranyle éventuellement substitué ou cyclohexyle éventuellement substitué; les substituants aux positions 2 et 6 sont choisis indépendamment parmi halogéno, alkyle inférieur C1-4, etc., et les substituants aux positons 3 à 5 et ceux du 9-anthranyle et du cyclohexyle sont choisis indépendamment non seulement parmi ceux mentionnés ci-dessus pour les positions 2 et 6, mais également parmi les groupes alkyle C5-6 substitués et non substitués, les groupes aryle substitués et non substitués, etc.; et les Ar peuvent être identiques ou différents.
