There is growing need to utilise Earth-abundant transition metal complexes in photovoltaic and photocatalytic applications, while reducing the current heavy reliance on rare, expensive and toxic heavy transition metal complex, such as Ru-based. Iron is the most abundant transition metal within the same group 8 as Ru while being very cheap and eco-friendly. But its photophysics suffers from the disadvantage of short excited-state lifetime of MLCT states due to low lying MC states. However ever since the introduction of NHC carbene-based ligands, the increased sigma donor strength has significantly improved the MLCT lifetimes and there has been a tremendous development in the last decade. This thesis delves into an extensive investigation of the photophysical and photochemical properties of diverse homoleptic and heteroleptic Fe-carbene complexes to unravel the influence of ligand architecture and design on excited-state dynamics. The primary objective of elucidating excited-state dynamics and deactivation pathways in relation to structure-property relationships. Expanding the scope of iron carbene complexes for functional applications is another key goal, achieved by introducing pH-sensitive functional ligands that hold immense significance for light-driven applications.

In recent years, great focus has been placed upon polymer thin films. These polymer thin films are important in many technological applications, ranging from coatings and adhesives to organic electronic devices, including sensors and detectors. Electrochemical polymerization is preferable, especially if the polymeric product is intended for use as polymer thin films, because electrogeneration allows fine control over the film thickness, an important parameter for fabrication of devices. Moreover, it was demonstrated that it is possible to modify the material properties by parameter control of the electrodeposition process. Electrochemistry is an excellent tool, not only for synthesis, but also for characterization and application of various types of materials. This book provides a timely overview of a current state of knowledge regarding the use of electropolymerization for new materials preparation, including conducting polymers and various possibilities of applications.

In less than 20 years N-heterocyclic carbenes (NHCs) have become well-established ancillary ligands for the preparation of transition metal-based catalysts. This is mainly due to the fact that NHCs tend to bind strongly to metal centres, avoiding the need of excess ligand in catalytic reactions. Also, NHC‒metal complexes are often insensitive to air and moisture, and have proven remarkably resistant to oxidation. This book showcases the wide variety of applications of NHCs in different chemistry fields beyond being simple phosphine mimics. This second edition has been updated throughout, and now includes a new chapter on NHC‒main group element complexes. It covers the synthesis of NHC ligands and their corresponding metal complexes, as well as their bonding and stereoelectronic properties and applications in catalysis. This is complemented by related topics such as organocatalysis and biologically active complexes. Written for organic and inorganic chemists, this book is ideal for postgraduates, researchers and industrialists.
