Synthesis and application of trifluoroethoxy-substituted phthalocyanines and subphthalocyanines
Phthalocyanines and subphthalocyanines are attracting attention as functional dyes that are applicable to organic solar cells, photodynamic therapy, organic electronic devices, and other applications. However, phthalocyanines are generally difficult to handle due to their strong ability to aggregate, so this property must be controlled for further applications of phthalocyanines. On the other h...
متن کاملSyntheses and properties of trimethylaminophenoxy-substituted Zn((II))-phthalocyanines.
The syntheses, photophysical properties and in vitro biological behavior of a series of nine Zn((II))-phthalocyanines (ZnPcs) bearing one to eight positively-charged trimethylaminophenoxy groups are reported. All ZnPcs are highly soluble in polar organic solvents, and show fluorescence and singlet oxygen quantum yields in the ranges 0.11-0.21 and 0.16-0.47, respectively. The cytotoxicity of the...
متن کاملOctathienyl/phenyl-substituted zinc phthalocyanines J-aggregated through conformational planarization.
A novel family of thiophene-decorated phthalocyanines (M-TPcs) was efficiently synthesized, during which the key intermediate of these compounds was purified through a chemical approach. In the optimized geometries of M-TPcs, the peripherally linked thiophene rings are tilted from the Pc core, which oppose aggregation considering the mutual steric hindrance. However, Zn-TPc formed J-aggregates ...
متن کاملEnhanced reverse saturable absorption and optical limiting in heavy-atom-substituted phthalocyanines.
The reverse saturable absorption and the optical-limiting response of metal phthalocyanines can be enhanced by use of the heavy-atom effect. Phthalocyanines containing heavy-metal atoms, such as In, Sn, and Pb, show a nearly factor-of-2 enhancement in the ratio of effective excited-state to ground-state absorption cross sections compared with those containing lighter atoms, such as Al and Si. I...
متن کاملSynthesis, photophysical and photochemical properties of tetra- and octa-substituted gallium and indium phthalocyanines
The synthesis, photophysical and photochemical properties of the tetraand octa-[4-(benzyloxyphenoxy)] substituted gallium(III) and indium(III) phthalocyanines are reported for the first time. The new compounds have been characterized by elemental analysis, IR, H NMR spectroscopy and electronic spectroscopy. General trends are described for quantum yields of photodegredation, fluorescence quantu...
