Comprehensive overview of molecular packing in different fields Molecular Design of Opto-Electronic Materials delivers insights on molecular packing and its practical applications, from basic knowledge of organic compounds as a single molecule to the aggregated state. The book reviews aspects of molecular packing including internal mechanisms, main effective factors, control methods, and preferred structures in various functional materials. Molecular Design of Opto-Electronic Materials includes information on: * Research methodology of molecular aggregation science, covering theoretical calculations, general methods, and other methods* Photoluminescence of molecular aggregates, covering fluorescence, thermally activated delayed fluorescence (TADF), and phosphorescence* Molecular aggregates as active layers in organic solar cells, covering effects of donor and acceptor aggregates* Molecular aggregates for second-order nonlinear optical effect, covering microscopic and macroscopic nonlinearities of organic systems, and organic molecules and polymers for second-order nonlinear optics* Other opto-electric materials in aggregate, including magnetic and radical materials as well as metal- and covalent-organic frameworks Molecular Design of Opto-Electronic Materials is an excellent reference for chemists, materials scientists, physicists, and electrical engineers involved in development of opto-electronic materials who are seeking to expand their knowledge bases and stay up-to-date with current applications.
