“…Thanks to these special and exclusive properties, Pcs have led to numerous interests in many fields, such as therapeutic medicine, photosensitizers for photodynamic therapy of cancer (PDT) [2] and antioxidant [3]. Besides, many otherapplications have appeared, including nonlinear optics [4], optical filters [5], liquidcrystalline electronic charge carriers [6], Langmuir-Blodgett films [7], chemical sensor [8], ink-jet printing [9], optical read-write disks [10], catalysis [11], layers of gas sensors [12]solar cells [13], exciton-transport materials, semi-conductors [14] in addition to their traditional use as dyes and pigments [15]. Due to the intermolecular interactions between the macrocycles, many metal free phthalocyanines(Pcs) and metallophthalocyanines compounds are generally insoluble in organic solvents.…”

Abstract:The novel phthalonitrile derivatives bearing methyl 2-mercaptoacetate and methyl 3-mercaptopropanoate phthalonitrile substituents at peripheral position were preparedby a nucleophilic displacement reaction. Cyclotetramerization of these phthalonitrile derivatives in the presence of corresponding metal salts gave the new metallophthalocyanines. The novel compounds were characterized by using various spectroscopic data. The aggregation investigations carried out in different concentrations indicate that phthalocyanine compounds do not have any aggregation behavior for the concentration range of 10 −4 -10 −6 M in tetrahydrofuran. In vitro three antioxidant test methods, namely (2, 2-diphenyl-1-picryl-hydrazyl) radical scavenging activity was used to determine the antioxidant activity of compounds. In addition to these, the antibacterial activities of compounds were investigated by using the disk-diffusion method.

Carbazole Substituted Pyridopyrimidine (CSPP) was synthesized and Charge transfer complexes with some acceptors such as tetracyanoquinomethane (TCNQ) and 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) have been studied spectrophotometrically in acetonitrile at 21 o C. The stoichiometries of the complexes were found to be 1:1 ratio by the Job method between donor and acceptors with the maximum absorption band at a wavelength of 715 nm for DDQ and 593 nm for TCNQ. The formation constants of the complexes were determined by Benesi-Hildebrand equation. The thermodynamic parameters were calculated by Van't Hoff equations and found spontaneous and exothermic.
