Small carbazole-based molecules as hole transporting materials for perovskite solar cells

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

“…In the FT-IR spectrum, the vibration bands of aromatic CH, aliphatic CH, and CuN groups appeared at 3095 cm −1 , 2959-2924 cm −1 , and 2233 cm −1 , respectively. In the 1 As shown in Scheme 1, template cyclotetramerization of dinitrile (1) in the presence of anhydrous metal salts resulted in phthalocyanine derivatives (2)(3)(4). All the compounds were characterized by performing several spectroscopic techniques including FT-IR, 1 H NMR, MALDI-TOF, and UV-vis spectroscopy.…”

“…Carbazoles are N-heterocyclic aromatic compounds that exhibit excellent fluorescence properties and form an important structural element of many compounds used for the manufacture of electronic materials, polymers, or dyes. [1][2][3] These compounds have high biological and pharmacological activities including anticancer, antimicrobial, antiviral, anti-inflammatory, and antioxidant activities. [4][5][6][7][8][9] In the literature, some carbazole derivatives have been considered potent anticancer agents owing to their high antiproliferative activities against various cancer cell lines.…”
