Their (1-3) structures were illuminated with spectroscopic methods such as FT-IR, 1H NMR,13C NMR, UV–vis, MALDI-TOF mass spectra and also elemental analysis. The spectroscopic, photophysical and photochemical properties of the zinc(II) phthalocyanine 3 were investigated in dimethyl sulfoxide and its effects on the above mentioned properties were reported as a result of containing new type benzenesulfonamide derivatives as substituents. In addition, its above-mentioned properties were reported by comparing different species with those of their substituted and/or unsubstituted counterparts. The zinc(II) phthalocyanine 3 has photosensitizing abilities suitable and sufficient especially for photocatalytic applications.

Novel octa-phenotiazine, octa-benzoazepine and octa-carbazole substituted magnesium(II) (MgPz-I-III) and zinc(II) (ZnPz-I-III) porphyrazines were synthesized from 2,3-bis[6-(4a,10a-dihydro-phenothiazin-10-yl)-hexylsulfanyl]-but-2-enedinitrile (5), 2,3-bis [6-(4a,11a-dihydro-dibenzo[b,f]azepin-5-yl)-hexysulfan-yl]-but-2-enedinitrile (8) and 2,3-bis(6-carbazol-9-yl-hexylsulfanyl)-but-2-enedinitrile (10), respectively. These dinitrile derivatives 5, 8 and 10 were also prepared by the reaction of 1,2-dicyano-1,2-ethylenedithiolate di-sodium salt (4) with 10-(6-bromohexyl)-10H-phenothiazine (3), 5-(6-bromohexyl)-5H-diben-zo[b,f]azepine (7) and 9-(6-bromo-hexyl)-9H-carbazole (9), respectively. Porphyrazino-zinc(II) complexes were synthesized by one-step reaction using Zn(BuO)[Formula: see text] as a template agent. All the novel compounds were characterized by elemental analysis and different spectroscopic methods such as [Formula: see text]H NMR, [Formula: see text]C NMR, FT-IR, UV-Vis and mass. The photochemical properties including photodegradation and singlet oxygen generation for magnesium(II) and zinc (II) porphyrazine complexes were studied in dimethylsulfoxide solutions for determination of their photosensitizer behaviors.

Novel series of diversely substituted acetyl pyrazoline having biphenyl carbonitrile motif have been synthesized. The reaction of 2-cyno-4’-bromomethyl biphenyl with1-(4-hydroxy-phenyl)-ethanone resulted in acetophenone derivative of biphenyl-2-carbonitrile. This acetophenone derivative was condensed with substituted aromatic aldehyde in mixed solvent resulted in various substituted chalcones. These chalcones were further cyclized using hydrazine hydrate in presence of glacial acetic acid to produce titled compound derivatives. The chemical structures of synthesized compounds were elucidated by 1H-NMR, 13C-NMR FT-IR and mass spectra. Synthesized compounds were screened for their antimicrobial activity by broth dilution method. Out of twelve newly synthesized compounds, eight compounds are found to be equipotent to Ampicillin.

The alkyl salicylaldoxime has attracted more and more attention recently due to the complex branched alkyl groups. In this study, a novel alkyl salicylaldoxime, tert-octylsalicylaldoxime, was successfully synthesized by the one-pot method. The yield and purity by the elemental analysis were 96.17 and 94.13%, respectively. The structure was confirmed by elemental analysis, FT-IR, 1H NMR (Nuclear Magnetic Resonance), 13C NMR spectroscopy, and MS. Results showed that tert-octylsalicylaldoxime with a new structure exhibited excellent extraction ability and selectivity for Cu(II) and can be successfully used to recover Cu from copper-nickel alloy electroplating wastewater. Thus, this product has the potential to be used as a powerful copper extractant in the future.
