Metal-organic frameworks optical properties

Both Buchwald and Hartwig have explored the use of palladium-catalyzed amination for the synthesis of dendrimers and polyanilines. Dendrimers, such as 48, can be easily assembled through sequential aiylation of aminoanilines.89 These dendrimers are useful in creating metal-organic frameworks and often can exhibit interesting electronic effects, such as diradicals, and as optical materials. Polymeric anilines 49 are of intense interest due to their unique electrical conducting properties. Using the... 

This is not to say that all has been discovered about these materials. New solids are continually being synthesised, and the rapidly developing field of porous metal organic frameworks (MOFs) is a current example. The applica-bihty of microporous solids is continually being extended within the traditional fields of adsorption, catalysis and ion exchange. One exciting application explores their use as catalysts in the manufacture of fine chemicals. Other emerging areas of research concern their potential use in medicine or in devices that require speeial electronic or optical properties. 

Metal-organic frameworks, often called MOFs, are a new class of inorganic-organic hybrid materials that have enormous potential for many practical applications [10]. They can combine the high nonlinear optical coefficients of the organic molecules with excellent physical properties of the inorganics, and may... 

On the other hand, the literature on fluoride crystallization is scarce, in spite of the recent work on nanosized fluoride particles for applications in optics or catalysisInterest in fluorides is mainly driven by their properties as crystallization agents for the synthesis of zeolites or phosphate-based materials and more recently of metal organic frameworks ° (MOF). Mixed anions (fluoride-phosphate, fluoride-carboxylate...) build three-dimensional 3D open frameworks for gas storage (CO2), catalysis or emerging applications (the symbols OD, ID, 2D, 3D, characteristic of the dimensionality of the frameworks, are used throughout this chapter). 

Metal organic co-ordination frameworks have attracted much interest recently [1-5] owing to their potential as materials for solvent-inclusion [6-11] or gas adsorption [12-15] or with electronic [16, 17] or non-linear optical properties [18,19]. The rational design and targeted synthesis of multidimensional molecular architectures is also of significance in the quest not only to understand how crystalline and ordered materials may be engineered [20-22], but also to elucidate the underlying processes of self-assembly [23-27].
