Abstract

In this paper, phthalonitrile (3) and it's zinc(II) (4) and magnessium (II) phthalocyanine (5) derivatives were prepared. The novel compounds (3-5) were characterized spectroscopically. The photochemical and photophysical properties compounds (4 and 5) were examined to determine whether they are suitable photosensitizers for PDT applications. The magnessium (II) phthalocyanine (5) produced low amount of singlet oxygen and high fluorescence quantum yield. However, the zinc(II) phthalocyanine (4) had potential to be used in PDT applications with it's high singlet oxygen production and high photostability. (C) 2020 Elsevier B.V. All rights reserved.
