Liquid crystalline octasubstituted lead(ii) phthalocyanines: effects of alkoxy and alkylthio substituents on film alignment and electrical properties

Optical, Electrochemical, Third-Order Nonlinear Optical Investigations of 3,4,5-Trimethoxy Phenyl Substituted Non-Aqueous Phthalocyanines

“…Phthalocyanines (Pcs) are large aromatic pigment molecules composed of four isoindole units linked by nitrogen atoms ( Giribabu et al, 2008 ). Unlike porphyrins, phthalocyanines are human-made compounds which have a wide range of advantages in diversified areas such as sensor technology, catalysts, electrochromism, liquid crystals, photodynamic therapy, and energy storage devices to name a few ( Gregory, 2000 ; Zagal et al, 2010 ; Tuncel et al, 2012 ; Kuzmina et al, 2019 ; Buyukeksi et al, 2020 ; Kumar et al, 2021b ; Halaskova et al, 2021 ). Because of their electronic delocalization, innumerable properties arise which make them of great potential in various fields of science and technology.…”

Synthesis and Properties of Sulfo and Alkylsulfamoyl Substituted CuII and NiII Phthalocyanines Bearing 1-Benzotryazolyl and 4-(1-Methyl-1-phenylethyl)phenoxy Groups

“…It is achieved by introducing aliphatic chains on phthalocyanine molecule periphery. [5,9] Moreover, possibility to form lyomesophases in binary systems with different solvents is a very important property of this phthalocyanine derivatives. [9,11] Solubility of this compounds in water is valuable property for their investigation and application.…”

“…[1][2][3][4][5][6] Phthalocyanine derivatives are quite interesting objects for such studies and widely used on many fields of science and technology. [7][8][9] Particularly phthalocyanines with volumetric substituents are very prospective materials for optoelectronic devices due to the ability of glass-like state formation [10] and light absorbtion in strongly fixed spectrum region.…”
