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.

The thesis provides the necessary experimental and analytical tools to unambiguously observe the atomically resolved chemical reactions. A great challenge of modern science has been to directly observe atomic motions during structural transitions, and while this was first achieved through a major advance in electron source brightness, the information content was still limited and new methods for image reconstruction using femtosecond electron diffraction methods were needed. One particular challenge lay in reconciling the innumerable possible nuclear configurations with the observation of chemical reaction mechanisms that reproducibly give the same kind of chemistry for large classes of molecules. The author shows that there is a simple solution that occurs during barrier crossing in which the highly anharmonic potential at that point in nuclear rearrangements couples high- and low-frequency vibrational modes to give highly localized nuclear motions, reducing hundreds of potential degrees of freedom to just a few key modes. Specific examples are given in this thesis, including two photoinduced phase transitions in an organic system, a ring closure reaction, and two direct observations of nuclear reorganization driven by spin transitions. The emerging field of structural dynamics promises to change the way we think about the physics of chemistry and this thesis provides tools to make it happen.
