This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Porphyrins are attractive building blocks for self-assembled functional nanomaterials because they can be modified with a wide range of substituents and they possess diverse photophysical and chemical properties that are potentially useful in applications such as solar energy conversion, molecular electronics, catalysis and sensors. Recently, ionic self-assembly of oppositely-charged porphyrin tectons has been shown to produce well-defined structures such as nanotubes and nanofiber bundles. The synthesis of a novel cationic porphyrin tecton, tin 5,10,15,20-tetrakis(4-piperidyl)porphyrin is described. This porphyrin can be self-assembled with porphyrins such as 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin that only ionize under neutral or basic conditions. The nanostructures and metalized nanocomposites obtained from the self-assembly reactions are characterized using electron microscopy and spectroscopic techniques. In addition the synthesis and characterization of zinc and tin complexes of T(N-EtOH-Py)P are described and the ionic self-assembly reactions of these compounds to produce cooperative binary ionic solids are discussed. Quadrone's complex tetracyclic skeletal structure has allowed it to serve as an excellent showcase molecule for total synthesis. Three distinct routes were developed and tested in hopes of achieving an elusive substituted 10-hydroxy-dec-8-ynoic acid. Route I explored the limits of 1,4-conjugate addition. We were able to reproduce work demonstrating the remarkable selectivity that organomanganese reagents show for 1,4-addition even when the beta-carbon bears germinal-dimethyl substitution. Unfortunately, the propargylic manganese reagent needed for addition could not be synthesized despite using a diverse set of conditions and reagents. The second route demonstrated that an 11-membered acetylenic lactone could be transesterified into the corresponding methyl ester. This methyl ester resisted hydrolysis in the most forcing conditions commonly used. In fact decomposition of the molecule was observed before hydrolysis was ever observed. Route III utilized the Ireland-Claisen rearrangement (ICR) to generate the highly hindered tertiary carbon alpha to the geminal dimethyl carbons. The early troubles encountered in route III were particularly surprising given the large amount of general literature precedence available for the ICR and test systems were synthesized to explore the reaction in more detail. We demonstrated that the alpha-carbon must be relatively unhindered for the reaction to proceed. When the alpha-carbon is hindered, like most of our systems were, the desired rearrengement does occur but in low yield, and unusual side reactions are observed. In the system designed for the synthesis we observe an elimination reaction that consumes the majority of the starting material. When we truncated the system to prevent elimination, a coupled product was isolated that does not appear to have been fully characterized in the literature. Our early explorations into the formation of this coupled product indicate that some reaction control exists. By not adding TMS-Cl to the reaction we have successfully prevented the ICR while still allowing the coupling reaction to occur. Additionally, it appears possible to control which isomer of the coupled product forms either through reaction time or equivalents of base present. Ultimately, further work exploring the ICR of substrates containing quaternary beta-carbons needs to be done. Our initial test systems lead one to believe that this coupling process is not unique and that more substrates have the potential to form this complex functional group.

This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Photodynamic therapy (PDT) agents are light-activated materials used for localized disease treatment. Porphyrins are classic representations of photosensitive agents. Identified by their large, planar molecular structure, porphyrins are centrally composed of four pyrrole rings. Through this project, the starting material, H2TPPC, a tetra-carboxylic acid porphyrin, was first synthesized and later modified through the addition of the amine, morpholin-2-ylmethanol. This multi-step synthesis resulted in the highly water-soluble porphyrin product H2TPP-MorphMeOH. Following this synthesis, the compound was purified using liquid chromatography, and then structurally identified and classified using infrared (IR), nuclear magnetic resonance (NMR), and UV-Vis spectroscopies. Lastly, to determine its utility as a potential PDT agent, the cytotoxicity of H2TPP-MorphMeOH was determined using an MTT assay on MDA-MB-231 triple negative breast cancer cells comparing exposure and absence of white light.

Kadish and published by World Scientific Publishing Company. This book was released on 2022-02-22 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research in the area of porphyrins, phthalocyanines and related macrocycles continues to expand at a phenomenal rate with literally thousands of original articles being published every year in the fields of chemistry, physics, biology, material science and photodynamic therapy. The current volume comprehensively summarizes key aspects involved in the synthesis, characterization and use of these compounds, as well as computational methodologies for the design of novel tetrapyrroles whose structural and electronic properties are described. Each chapter is authored by an expert or group of experts in the field who were asked to write 'a review for the ages' and we anticipate that what is written in this volume will remain relevant for at least the next 15 years, and possibly longer.This volume should be considered as required reading for both new and experienced researchers in a number of sub-disciplines where tetrapyrroles are studied or utilized in a variety of applications. A complete understanding of the chemistry of these compounds necessitates not only a knowledge of what has been accomplished in the area of synthesis and characterization but also a knowledge of what is possible in the future when using porphyrins and related tetrapyrroles as key components for applications in catalysis, energy production and biomedical applications.
