This research aims to elucidate the use of supramolecular interaction to guide the formation of well-defined nanoscale self-assembled architecture in photovoltaic solar cells as a means to improve device efficiency. Complementary molecular recognition sites based on melamine and barbituric acid were used to obtain functionalized fullerene and oligothiophene materials with superior processibility thanks to the presence of specific solubilizing groups. The efficiency of solid-state devices fabricated using the bulk heterojunction design was studied with respect to device morphology and composition. Experiments on recombination mechanism and field effect mobilities suggest that the balance between hydrogen-bonding interactions induce self-assembly and p-p interactions to promote phase segregation is crucial to the micro-structure of the active layer. The investigated of the relationship between the oligothiophene chain size and various complementary hydrogen-bonding motifs is envisaged.

Perspectives in Supramolecular Chemistry relates recent developments and new exciting approaches in supramolecular chemistry. The series covers all areas from theoretical and modelling aspects through organic and inorganic chemistry and biochemistry to materials, solid-state and polymer sciences reflecting the many and varied applications of supramolecular structures in modern chemistry. From the early days of supramolecular chemistry the field has been associated with possible applications. This is not surprising as the design of new molecules, and later of assemblies of molecules, is often function-driven. Now, after three decades of supramolecular chemistry, David Reinhoudt has brought together a collection of reviews to reflect on the applications that have actually been achieved. The first applications in molecular recognition are now established technologies in analytical chemistry, separation science and medicine. More recently, developments have taken place in material design and these concepts are also discussed here. Contents * Self-Assembling Systems on Scales from Nanometers to Millimeters: Design and Discovery * Dendritic Architectures * Supramolecular Structures with Macromolecules * Chemosensors: Synthetic Receptors in Analytical Sensing Applications * Selective Ion Recognition with Durable Sensors * Ion Separations in Membrane and Solid Phase Extraction Systems * Porphyrin- and Expanded Pophyrin-Based Diagnostic and Therapeutic Agents Supramolecular Materials and Technologies illustrates the achievements and advances that supramolecular chemistry has made in many fields from organic chemistry to materials science and from analytical chemistry to molecular biology.

As one of the typical intermolecular interactions, hydrogen-bonding plays a significant role in molecular structure and function. When the hydrogen bond research system is connected with the photon, the hydrogen-bonding effect turns to an excited-state one influencing photochemistry, photobiology, and photophysics. Thus, the hydrogen bond in an excited state is a key topic for understanding the excited-state properties, especially for optoelectronic or luminescent materials.The approaches presented in this book include quantum chemical calculation, molecular dynamics simulation and ultrafast spectroscopy, which are strong tools to investigate the hydrogen bond. Unlike other existing titles, this book combines theoretical calculations and experiments to explore the nature of excited-state hydrogen bonds. By using these methods, more details and faster processes involved in excited-state dynamics of hydrogen bond are explored.This highly interdisciplinary book provides an overview of leading hydrogen bond research. It is essential reading for faculties and students in researching photochemistry, photobiology and photophysics, as well as novel optoelectronic materials, fluorescence probes and photocatalysts. It will also guide research beginners to getting a quick start within this field.
