Excitation Energies and Properties of Open-Shell Singlet Molecules PDF Author: Masayoshi Nakano
Publisher: Springer
ISBN: 3319081209
Category : Science
Languages : en
Pages : 129

Book Description
This brief investigates the diradical character, which is one of the ground-state chemical indices for "bond weakness" or "electron correlation" and which allows researchers to explore the origins of the electron-correlation-driven physico-chemical phenomena concerned with electronic, optical and magnetic properties as well as to control them in the broad fields of physics and chemistry. It then provides the theoretical fundamentals of ground and excited electronic structures of symmetric and asymmetric open-shell molecular systems by using model molecular systems. Moreover, it presents the theoretical design guidelines for a new class of open-shell singlet molecular systems for nonlinear optics (NLO) and singlet fission.

Polycyclic Arenes and Heteroarenes

Polycyclic Arenes and Heteroarenes PDF Author: Qian Miao
Publisher: John Wiley & Sons
ISBN: 3527338470
Category : Science
Languages : en
Pages : 356

Book Description
The first book of its kind to focus on the chemistry of this promising class of molecules. Edited by an innovator in the field, who has gathered an international team of well-established experts, this is a comprehensive overview of the rapidly developing field of polycyclic (hetero)arenes, specifically highlighting on their molecular design and the latest synthetic procedures, as well as chemical and physical properties. Each chapter is dedicated to a specific compound class, the first eight covering polycyclic arenes, including both planar and non-planar conjugated molecules, while chapters nine to twelve deal with polycylic heteroarenes according to the heteroatoms, namely N, B, S and P. Important current and emergent applications in the field are also discussed, ranging from molecular sensors to electronic devices. The result is an essential reference for researchers in synthetic and physical organic chemistry, supramolecular chemistry, and materials science.

Diradicaloids

Diradicaloids PDF Author: Jishan Wu
Publisher: CRC Press
ISBN: 1000565254
Category : Science
Languages : en
Pages : 638

Book Description
π-Conjugated molecules with an even number of π-electrons usually have a closed-shell ground state. However, recent studies have demonstrated that a certain type of molecules could show open-shell singlet ground state and display diradical-like (diradicaloid) behavior. Their electronic structure can be understood in terms of the “diradical character” and “aromaticity” concepts. They display very different electronic properties from traditional closed-shell π-conjugated molecules and could be used as next-generation molecular materials. This book provides a comprehensive review on the chemistry, physics, and material applications of open-shell singlet diradicaloids. Particularly, it elaborates the fundamental structure–diradical character–electronic property relationships both theoretically and experimentally. The book has been written by leading scientists in the field from Japan, Germany, Spain, Italy, China, and Singapore.

Physical Organic Chemistry of Quinodimethanes

Physical Organic Chemistry of Quinodimethanes PDF Author: Yoshito Tobe
Publisher: Springer
ISBN: 3319933027
Category : Science
Languages : en
Pages : 283

Book Description
The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.

Recent Advances in Density Functional Methods

Recent Advances in Density Functional Methods PDF Author: Delano Pun Chong
Publisher: World Scientific
ISBN: 9789810231606
Category : Mathematics
Languages : en
Pages : 344

Book Description
Of all the different areas in computational chemistry, density functional theory (DFT) enjoys the most rapid development. Even at the level of the local density approximation (LDA), which is computationally less demanding, DFT can usually provide better answers than Hartree-Fock formalism for large systems such as clusters and solids. For atoms and molecules, the results from DFT often rival those obtained by ab initio quantum chemistry, partly because larger basis sets can be used. Such encouraging results have in turn stimulated workers to further investigate the formal theory as well as the computational methodology of DFT.This Part II expands on the methodology and applications of DFT. Some of the chapters report on the latest developments (since the publication of Part I in 1995), while others extend the applications to wider range of molecules and their environments. Together, this and other recent review volumes on DFT show that DFT provides an efficient and accurate alternative to traditional quantum chemical methods. Such demonstration should hopefully stimulate frutiful developments in formal theory, better exchange-correlation functionals, and linear scaling methodology.

N-Heterocyclic Carbenes

N-Heterocyclic Carbenes PDF Author: Silvia Diez-Gonzalez
Publisher: Royal Society of Chemistry
ISBN: 1782626816
Category : Science
Languages : en
Pages : 637

Book Description
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.
