Book Description
Binuclear phthalocyanines in which two different phthalocyanine nuclei are covalently linked through five-atom bridges, derived from 2-ethyl-2-methylpropan-1,3-diol are prepared. In the examples, one phthalocyanine ring is always substituted with neopentoxy substituents, while the other phthalocyanine ring is unsubstituted or contains a tert-butyl substituents or a neopentoxy substituted copper phthalocyanine, constituting a biculear phthalocyanine in which only one ring is metallated. The precursor, 2-(2-hydroxymethyl-2-methylbutoxy)-9,16,23-trineopentoxyphthalocyanine41 was prepared in solution and also by solid phase methods, using polymer-bound trityl chloride derived from a 1% divinylbenzene-co-styrene co-polymer. Keywords: Phthalocyanine, Binuclear, Pentanuclear, Polymer support. (jes).

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.

Book Description
FUNDAMENTALS OF PORPHYRIN CHEMISTRY An indispensable and concise overview of the chemistry of porphyrins and related molecules In Fundamentals of Porphyrin Chemistry: A 21st Century Approach, a team of distinguished researchers delivers a compact and accessible introduction to the broad field of porphyrin chemistry. It discusses the basics of porphyrin synthesis and structure, as well as that of related molecules, and the current and future roles that porphyrins play in chemical transformations, materials design and synthesis, energy capture and transduction, human health, and the environment. This edited volume is a self-contained tutorial on concepts of critical importance to porphyrin chemistry and serves as the foundation for discussions about the applications of porphyrin-related compounds found in the second volume. This book contains: A thorough introduction to porphyrins, including their structure, nomenclature, naturally occurring porphyrins, synthetic porphyrins, and common families of porphyrin-related compounds Comprehensive explorations of chemical porphyrin synthesis, including how to synthesize porphyrins from simple, symmetric, and advanced ABCD-substituted porphyrins Practical discussions of the physical characteristics of porphyrins, including their structural features, electronic structure, spectroscopy, magnetism, electrochemistry, and electron transfer processes Perfect for experienced academic researchers in the field of porphyrin chemistry seeking a quick reference, Fundamentals of Porphyrin Chemistry: A 21st Century Approach is also an indispensable resource for researchers new to the field who need an overview directing them to literature in more focused areas.

Book Description
Applications of low symmetry subphthalocyanines (SPcs) are steadily rising in high technological fields due to their unique photochemical properties and their ability to be used as precursors for the synthesis of unsymmetrical phthalocyanines. The synthetic route to these compounds allow diversity in structure that can be fine-tuned for niche applications. Herein, we report the synthesis of mixed fluorinated phenylthio-SPcs of the forms SPc(A[subscript n]B3-[subscript n]) and SPc(A[subscript n]C3-[subscript n]) where 'A' is tetrafluorobenzo-, 'B' is 1,4-bis(phenylthio)benzo-, and 'C' is 1,4-bis(phenylthio)naphtho- (n = 1,2). The complete characterization by HR-LCMS, 1H NMR, 19F NMR, HPLC and UV-Vis proves both identity and purity of boron 1,2,3,4-tetrafluoro-8,11,15,18-octakis(phenylthio)subphthalocyanine chloride SPc(AB2)), birib 1,2,3,4,8,9,10,11-octafluoro-14,18-bis(phenylthio)subphthalocyanine (SPc(A2B)), boron 1,2,3,4-tetrafluoro-dinaphtho[b, g]-8,14,18,23-tetrakis(phenylthio)subphthalocyanine chloride (SPc(AC2)), and boron 1,2,3,4,8,9,10,11-octafluoro-naphtho[b]-16,21-bis(phenylthio)subphthalocyanine chloride SPc(A2C)).
