Karl Michael Ziems investigates a meso-mesityl-2,6-Iodine substituted Boron Dipyrromethene (BODIPY) dye regarding its functionality as photosensitizer in a two-component light-driven hydrogen evolution. The author uses quantum chemical calculations performed at the time-dependent density functional (TDDFT) and multi-state restricted active space perturbation theory through second-order (MS-RASPT2) level of theory. The light-induced processes associated with the formation of the active photosensitizer, i.e., by means of charge separation, as well as the population of undesired degradative pathways are elucidated. Hereby, the two proposed and investigated mechanisms are based on a heavy atom effect of iodine in the (excited) singlet/triplet manifold and preliminary reduction (of the dye) by a sacrificial electron donor and subsequent photoexcitation.

This book covers the broad field of cellular, molecular, preclinical, and clinical imaging either associated with or combined with photodynamic therapy (PDT). It showcases how this approach is used clinically for cancer, infections, and diseases characterized by unwanted tissue such as atherosclerosis or blindness. Because the photosensitizers are also fluorescent, the book also addresses various imaging systems such as confocal microscopy and small animal imaging systems, and highlights how they have been used to follow and optimize treatment, and to answer important mechanistic questions. Chapters also discuss how imaging has made important contributions to clinical outcomes in skin, bladder, and brain cancers, as well as in the development of theranostic agents for detection and treatment of disease. This book provides a resource for physicians and research scientists in cell biology, microscopy, optics, molecular imaging, oncology, and drug discovery.

This book, Organic Polymers, covers aspects that are of immediate concern to a new entrant to the field of polymers. Taken as a whole, these eight chapters aim to help the readers easily assimilate other specialized and exhaustive treatises on the subject. Topics dealing with the chemistry and technology of polymers are presented in a careful and logical manner so as to provide an easy and enjoyable read. Several examples and analogies are included so to make the main concepts easy to follow and tables and figures are included so that the book can serve, to a limited extent, as a hand book dealing with polysaccharides with different parameters. This book is meant for students studying polysaccharides and those working on graft copolymers and other allied polymer industries but without a formal educational background in organic polymers.

This book covers a wide range of topics related to functional dyes, from synthesis and functionality to application. Making a survey of recent progress in functional dye chemistry, it provides an opportunity not only to understand the structure-property relationships of a variety of functional dyes but also to know how they are applied in practical use, from electronic devices to biochemical analyses. From classic dyes such as cyanines, squaraines, porphyrins, phthalocyanines, and others to the newest functional π-conjugation systems, various types of functional dyes are dealt with extensively in the book, focusing especially on the state of the art and the future. Readers will benefit greatly from the scientific context in which organic dyes and pigments are comprehensively explained on the basis of chemistry.

Photodynamic therapy utilizes photosensitizers together with irradiating light of specific wavelengths interacting with oxygen to generate cytotoxic reactive oxygen species, in particular singlet oxygen, for clinical treatment of several malignant and non-malignant pathologies. Recently, enhanced photodynamic therapy was successfully achieved by using new light sources (i.e., light-emitting diode), novel functional nano-photosensitizers, oxygen supply and synergistic therapy. In addition, photodynamic therapy has been increasingly used in the fields of antimicrobial and antibiofilm activities. This two-volume work highlights the state-of-the-art in enhanced photodynamic therapy for clinical applications.
