Book Description
Phthalocyanines and other closely related compounds are an important class of macrocycles with many commercial applications. They display interesting optoelectronic and coordination properties, which has resulted in their utilisation in a wide range of fields including optical data storage, electrochromic and optical limiting devices, photosensitizers and medicinal therapeutic agents, and multistage-redox-dependent fluorophores. The synthesis, optoelectronic and surface-assembly properties of several new axially disubstituted silicon phthalocyanines are detailed in this work. Axial ligands include phenyl, terphenyl, thienyl and pyrenyl derivatives. Their absorption and emission spectra are reported and fluorescence lifetimes and quantum yields are correlated with the ligand structures. The optoelectronic properties of a novel free-base phthalocyanine bearing peripherally attached fluorene substituents are also described. Several of these silicon-phthalocyanines were used to assemble thin films on electrode surfaces, and techniques such as scanning Kelvin nanoprobe microscopy and atomic force microscopy, as well as chronoamperometric measurements were used to probe these surfaces. A number of free-base porphyrins bearing a variety of aryl substituents at the meso-positions are also described. The conversion of some of these free-base porphyrins to metalloporphynns is detailed, and a thorough examination of the fluorescence properties of all synthesised porphyrins is also presented. Pyrazinoporphyrazines are a closely-related analogue of phthalocyanines, and several new examples of these systems have been synthesised. As with both the phthalocyanines and porphyrins, their fluorescence properties have been investigated in detail.

Phthalocyanines and Some Current Applications
Author: Yusuf Yilmaz
Publisher: BoD – Books on Demand
ISBN: 9535132555
Category : Science
Languages : en
Pages : 255
Book Description
Since their initial accidental synthesis and characterization in Scotland in the late 1920s, there has been a strong research focus on the use of phthalocyanines (Pcs) as dyes and pigments. In recent years, active research fields have included their use in electrophotography, photovoltaic and solar cells, molecular electronics, Langmuir-Blodgett films, photosensitizers, electrochromic display devices, gas sensors, liquid crystals, low-dimensional conductors, and optical disks. Phthalocyanines possess interesting biological, electronic, optical, catalytic, and structural properties. The main disadvantage is their insolubility in common solvents due to strong intermolecular - interactions. The solubility of phthalocyanines can be increased by various methods such as the formation of anionic and cationic species and both axial and peripheral substitution. Substitution at the nonperipheral and peripheral positions of the benzo moieties usually enhances their solubility in organic solvents. The most important advantage of phthalocyanines compared to porphyrins is that their Q bands lie at longer wavelengths and are considerably more intense. In this book, you will find synthesis and some applications of various phthalocyanine derivatives.

Pages : 329
Book Description
Phthalocyanines exhibit intriguing physic-chemical properties that render them important as a class of molecular functional materials. In addition to their tra- tional industrial applications as dyes and pigments, more recently their use as the organic semiconductors, photodynamictherapy medicines, non-linear optical ma- rials, catalysts for the photo oxidation, optical recording materials, and gas sensors attracts great research interests in these tetrapyrrole species. As manifested by the rapidly increasing number of related scienti?c publications in recent years, great progress has been made in the ?eld of advanced phthalocyaninematerials. Tremendous efforts have been paid toward the development of new phtha- cyanine molecular materials as well as toward their applications. Recent emphasis in both academic researches and technical ?eld has been put on the design and synthesis of novel phthalocyanine species, the structure-propertyrelationship, se- assembly properties, molecular electronics and opto-electronics, and dye-sensitized solarcells.Althoughexcellentreviewsandmonographsaboutphthalocyanineswere publishedseveralyearsago, it is time to providea surveyof a numberof newimp- tant developments in this fascinating area of phthalocyanine chemistry.
