ItemContinuous Flow Synthesis of Conjugated Polymers and Carbon Materials(WILEY-V C H VERLAG GMBH, 2017)The basic equipment associated with the synthesis of chemicals in the laboratory has remained essentially unchanged since the establishment of chemistry as a scientific discipline. Most techniques and apparatus are optimized for batch-by-batch processes. These traditional batch techniques have the benefit of familiar and time-tested methodology and low up-front cost, and therefore the shift to more modern apparatus requires some additional motivating factors. Continuous flow processing is a technique which involves a nontrivial initial investment of both time and finances, but which offers significant benefits to synthetic chemists. Continuous flow processing has been increasing in prominence in the research laboratory setting in the last decade, and a number of research groups now specialize in the development of methods for flow processing. This progress is buoyed by the commercial availability of the associated equipment, which can now be purchased from several vendors.

ItemAggregation-induced emitters in light harvesting(Springer, 2019)Light harvesting is an integral part of energy conversion of sunlight into chemicals and electricity. In this chapter, the application of materials with aggregation-induced emission properties in artificial photosynthesis and photon refining technologies is summarized and discussed. In artificial photosynthesis, aggregation-induced emitters enable efficient energy transfer in self-assembled arrays. Thin film luminescent solar concentrators have also been made possible by aggregation-induced emitters as high concentrations of these chromophores can be used in such devices. Aggregates are also important in photon upconversion where proximity of chromophores enables efficient triplet energy transfer and triplet-triplet annihilation processes.

ItemValence Tautomerism in D‐Block Complexes(Wiley, )Abstract The need for both improved energy efficiency of information communication technologies, and increased data storage density to meet the requirements of contemporary society, has enhanced interest in the miniaturization of electronic devices. The ultimate in miniaturization is a single molecule and the possibility of utilizing individual molecules as device components has afforded the scientific field of molecular materials. So‐called “smart” materials respond to an external stimulus and such stimuli‐response can be achieved at the molecular level. Molecular materials that can be switched between forms with different electronic structures in response to an external stimulus offer the possibility of controlled switching between species with different physical and electronic properties, including most obviously, color. The phenomenon of valence tautomerism (VT) involves stimulated intramolecular electron transfer between a redox‐active metal and ligand, sometimes accompanied by a spin transition at the metal center. While best known for cobalt–dioxolene systems, other redox‐active metal and ligand combinations can also display VT. Known since 1980, in recent times, the field of VT has expanded in a range of directions, spanning from enhancing understanding of the fundamental science and development of new examples, to incorporation of VT species into technologically relevant media, including nanoparticles, thin films, and deposition on surfaces. Particularly exciting are developments in the use of density functional theory calculations, which now allow for accurate evaluation of the likelihood and characteristics of potential VT transitions in yet‐to‐be synthesized compounds. This article presents the fundamental aspects of valence tautomerism in d‐block complexes before comprehensibly describing recent developments and possible future implications.
