The synthesis and photophysical properties of novel, symmetrical, hexadecasubstituted Zn phthalocyanines and related unsymmetrical derivatives

Synthesis, electrochemistry and in situ spectroelectrochemistry of novel hexadeca-substituted phthalocyanines with three different groups

“…Although the synthesis of tetra-and octa-substituted phthalocyanine derivatives has attracted a great deal of interest, papers on synthesis of hexadeca-substituted phthalocyanine derivatives have been relatively few [27][28][29]. Recently, our group concentrated on synthesizing and understanding the properties of hexadecasubstituted phthalocyanines [20,30,31].…”

A Honeycomb-Like Crystalline Self-Assembled Hexadeca-Substituted Phthalocyanine

“…Pc macrocycle has sixteen positions which can be substituted. Unlike tetra‐ and octa‐ substituted derivatives of Pcs, fully substituted derivatives, namely hexadeca‐substituted Pcs are less studied in the literature . In hexadeca substitution pattern, the Pc ring environment is sterically crowded with substituents and, consequently, interactions between Pc cores are lowered both in liquid and solid state.…”

“…Unlike tetra-and octa-substituted derivatives of Pcs, fully substituted derivatives, namely hexadeca-substituted Pcs are less studied in the literature. [3] In hexadeca substitution pattern, the Pc ring environment is sterically crowded with substituents and, consequently, interactions between Pc cores are lowered both in liquid and solid state. Due to this property, hexadeca substitution can be beneficial for some applications such as photodynamic therapy (PDT) where aggregation is not desired.…”

Novel Hexadeca-Substituted Metal Free and Zinc(II) Phthalocyanines; Design, Synthesis and Photophysicochemical Properties

“…Hexadeca-substituted phthalocyanines are relatively less studied compared to tetra- or octa-substituted counterparts [13,14]. These phthalocyanines are also useful compounds for PDT [15], catalyst [16], optical materials [17], and Langmuir-Blodgett films [18].…”
