Abstract

A novel Frétchet structural dendritic substituted photosensitizer, tetra-{3,5-di-[3,5-di- (4-carboxylic benzyloxy) benzyloxy] benzyloxy} zinc (Ⅱ) phthalocyanine 6, was synthesized by the following steps. Firstly, 3,5-di-(4-cyanobenzyloxy) benzyl alcohol (1) was obtained by reaction of 3,5-di-hydroxybenzyl alcohol with p-cyanobenzylbromide. Then, 3,5-di-(4-cyanobenzyloxy) benzyl bromide (2) was synthesized by the reaction of 1 with carbon tetrabromide in the presence of triphenylphosphine and tetrahydrofuran. Following, 2 reacted with 3,5-di-hydroxybenzyl alcohol to afford 3,5-di-[3,5-di-(4-cyanobenzyloxy) benzyloxy] benzyl alcohol (3). The fragment 4-{3,5-di-[3,5-di-(4-cyanobenzyloxy)benzyloxy]} phthalonitrile (4) was obtained by reaction of 3 with 4-nitrophthalonitrile. Tetra-{3,5-di-[3,5-di-(4-cyanobenzyloxy) benzyloxy] benzyloxy} zinc(Ⅱ) (5) was obtained by condensation of 4 with acetate zinc and 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU) in n-pentanol. The tetra-{3,5-di-[3,5-di-(4-carboxylic benzyloxy) benzyloxy] benzyloxy} phthalocyanine zinc(Ⅱ) (6) was obtained by hydrolyzed 5 in NaOH. The structures of above compounds were characterized by a combination of methods including elemental analysis, 1H NMR, IR, ESI-MS and MALDI-TOF-MS. The photophysical properties of 5 and 6 were studied by UV/Vis, steady state and transient fluorescence spectrometry. The compound 6 is a kind of good performance of dendritic photosensitizer.
