Abstract

The synthesis of a new phthalonitrile 1 was described by treating 3-nitrophthalonitrile with 4- 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecylthio phenol. After that, its soluble zinc II 2 , magnesium II 3 , cobalt II 4 and indium chloride III 5 non-peripheral phthalocyanine derivatives were reported for the first time. The newly synthesized metallo phthalocyanine derivatives were characterized by mass spectrometry, UV-Vis, FT-IR, and 1H-NMR spectroscopy. Photochemical and photophysical photodegradation, singlet oxygen and fluorescence quantum yields properties of the phthalocyanines were carried out in tetrahydrofuran THF . Metallo-phthalocyanines, which containing a bulky long alkyl chain bearing fluorine atoms, have high solubility in known organic solvents such as THF, dichloromethane DCM , chloroform CHCl3 and toluene and do not show aggregation. Besides, the effect of metal ion types in phthalocyanines core 2, 3, 4 and 5 were also investigated. The effects of the substitution with fluoroalkynyl-functionalized groups on these parameters mentioned were also compared along with the previously synthesized peripherally tetra and octa substituted phthalocyanines. Non peripherally position of the substituents on Pc improved photophysical and photochemical properties.

Yeni Flor Zincirli Çözünür Ftalosiyaninler: Sentezi, Karakterizasyonu, Fotokimyasal ve Fotofiziksel Özellikleri

Abstract

B u çalışmada yeni 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10 3-nitroftalonitril ve onun çözünebilir non-peripheral çinko II 2 , magnezyum II 3 , kobalt II 4 ve indiyum klorür III 5 ftalosiyanin türevlerinin sentezi ilk kez rapor edildi. Yeni sentezlenmiş metalo ftalosiyanin türevlerinin yapıları, kütle, UV-Vis, FT-IR, ve 1H-NMR spektroskopisi kullanılarak karakterize edildi. Fotokimyasal Singlet Oksijen foto bozunma kuantum verimleri ve fotofiziksel floresans kuantum verimleri özellikleri tetrahidrofuran THF içinde incelendi. Flor atomları taşıyan uzun alkil zincirli gruplar taşıyan metallo fitalosiyaninlerin , THF, diklorometan DCM , kloroform CHCI3 ve toluen gibi bilinen organik çözücülerde yığılma göstermeden yüksek çözünürlüğe sahip oldukları görüldü. Bunun yanı sıra, merkez metal iyon türü ve substitüentin pozisyon etkisi daha önceki çalışmalarla karşılaştırılarak çalışıldı. Non peripheral konumun fotofiziksel ve fotokimyasal özellikleri geliştirdiği gözlendi
