The effect of phthalocyanine's periphery on the biological activities of carbazole-containing metal phthalocyanines

Abstract

This study reports the synthesis and characterization of two new mono- and di-substituted phthalonitriles namely 4-((9H-carbazol-3-yl)oxy)-5-chlorophthalonitrile and 4,5-bis((9H-carbazol-3-yl)oxy)phthalonitrile, respectively. Cyclotetramerization of the new phthalonitriles in the presence of zinc (II)...

Design of N-heterocycle based-phthalonitrile/metal phthalocyanine–silver nanoconjugates for cancer therapies

“…In addition, the size of silver nanoparticles increased from 10–15 nm to 20–25 nm, since the π–π interactions made these particles to approach and resulted in high aggregation and agglomeration. 19,60,61…”

“…Phthalocyanine-silver nanoconjugates were prepared as described in ref. 19, 60 and 61. Briefly, each compound ( 1–4 ) (10 mg) was dissolved in dimethyl sulfoxide (DMSO, 1 mL) and added to the aqueous solution of the silver nanoparticles (9 mL).…”

“…The mixture was vigorously stirred for 12 hours at room temperature, filtered off, and dried. 19,60,61…”

Supercapacitive properties of carbazole-containing cobalt(ii) phthalocyanines/reduced graphene oxide composites

“…Materials 3-(9H-Carbazol-2-yloxy)-phthalonitrile, 4-(9H-carbazol-2-yloxy)phthalonitrile, and 4,5-bis((9H-carbazol-3-yl)oxy)phthalonitrile were synthesized as described in the literature with some modifications. 32,35,40 Graphene oxide (GO) was synthesized using graphite powder (Acros-organics), H 2 SO 4 (Aldrich), H 3 PO 4 (Merck), KMnO 4 (Sigma-Aldrich), and H 2 O 2 (30%) (Aldrich). Deionized water (DI), acetone (Isolab), and absolute ethanol (Merck) were consecutively utilized to rinse electrodes.…”

“…Since the effects of carbazole groups on the chemical, physical, and optical properties of phthalocyanines have been rarely studied, our group has been interested in research on scientific features of novel carbazole-containing phthalocyanines in recent years. [37][38][39][40] Carbazoles include an aromatic nitrogen-containing tricyclic structure and exhibit high charge transfer, environmental resistance, chemical stability, and ease of functionalization, which make them efficient agents for many applications. 41 Recently, their potential utility in electrochromic rechargeable batteries has been investigated owing to their excellent electrochromic and photoconductive properties.…”
