Crystal structure-solid state reactivity relationships

Crystal Structure-Solid-State Reactivity Relationships... 

Many aspects of the preparation and properties of polydiacetylenes are the subject of lively debate. This review presents recent results that bear on some of these controversies. First the relationship of diacetylene monomer crystal structure and solid-state reactivity is discussed. Secondly the temporal evolution of solvato-chromio transitions of soluble polydiacetylenes is displayed. Optical and Raman spectra reveal the occurrence of an intermediate form of the polymer. A model compatible with these results is described.

The second part of the book compiles some practical aspects of metal oxides, with emphasis in catalytic applications. Metal oxides represent an expanding class of compounds with a wide range applications in several areas such as materials science and catalysis, chemical sensing, microelectronics, nanotechnology, environmental decontamination, analytical chemistry, solid-state chemistry, and fuel cells. Our basic knowledge on the metal oxide chemistry is relatively far from that for metals, and as yet, little is known about fundamental relationships between reactivity of oxide compounds and their chemical compositions, crystal structures, and electronic properties at the surface. When examining the importance of metal oxides, and specifically TMOs, in several reactions such as dehydration, selective oxidations, olefin metathesis, VOCs removal, photocatalysis, water splitting, and electrocatalysis, attempts will be made in order to connect properties of the oxides and their reactivity. Since the catalytic phenomenon is confined to the external surface of the solids where molecules or atoms interact, the study of this interaction... 

The first systematic study concerning the relationship between the chemical reactivity of an organic solid and its crystal structure is generally associated with the work of Schmidt and his co-workers on the photodimerization of cinnamic acid and its derivatives. The main conclusions were summarized by Schmidt in 1971 and phrases such as topochemistry and crystal engineering were set to enter the lexicon of the organic solid state chemist. ...
