New phthalonitrile/metal phthalocyanine–gold nanoparticle conjugates for biological applications

Abstract

The appearance of nanoscience and its effect on the development of the scientific fields particularly materials chemistry have been well-known today. In this study, a new di-substituted phthalonitrile derivative namely...

Anticancer activity of novel silicon phthalocyanines against the colorectal adenocarcinoma cell line (DLD-1)

“…In the mass spectra of compounds (2-Si, 3-Si, 2-QSi, and 3-QSi), molecular ion peaks were obtained at 1113. 32…”

“…26,27 The potent utility of phthalocyanines has been explored in the well-known scientific and technological fields that encompass electronics, sensing, medicine, and nanotechnology. [28][29][30][31][32][33][34][35][36][37] Since most of these applications require soluble materials, the insolubility of unsubstituted phthalocyanines in common organic and aqueous media is known as an essential limitation for their use in these fields. Introduction of bulky or long substituents on the periphery of phthalocyanines and insertion of metal cations into the phthalocyanine cavity increase the distance between the phthalocyanine rings and decrease the intermolecular interactions.…”

“…Therefore, substituted metal phthalocyanines bearing organic or quaternized organic groups exhibit higher solubility in organic solvents or water. [26][27][28][29][30][31][32][33][34][35][36][37][38] In comparison to non-peripheral and peripheral substituents, axial ligands cause more distance between phthalocyanine rings. As a result, the p-p interaction between the rings highly diminishes and the solubility of phthalocyanines increases.…”

Effects of aggregation on the structures and excited-state absorption for zinc phthalocyanine

“…1–5 Previous investigations indicated that phthalocyanine and its derivatives can be widely used in various research fields, such as sonodynamic therapy (SDT), 6,7 industrial textile colorants, 8 molecular electronics materials and imaging, 9,10 optical limiters 11,12 and other various organic electronic devices. 13,14…”

Antifungal Activity and Staining Properties of Some Symmetrically Functionalized Metal Phthalocyanine Dyes

“…Substituted metal phthalocyanine complexes and their gold nanoparticle and graphene conjugates have been known to exhibit antibacterial and photodynamic antibacterial activities. Representative precedents are mentioned here [28][29][30][31][32].…”
