dc.description.abstract | The metal-organic framework (MOF) compounds exhibit interesting
developments in coordination chemistry, materials science and other branches of
chemistry. These compounds have potential applications in diverse fields that include
gas separation, storage, catalysis, conductivity and water purification, etc. The MOFs are
a class of crystalline inorganic-organic hybrid compounds formed with metal nodes and
organic linking units. Such compounds can be prepared either by one-pot synthesis or by
sequential synthesis. In one-pot synthesis, the organic linkers with binding sites are
directly allowed to interact with the metal salts in a single pot. On the other hand, in
sequential synthesis, the pre-prepared metalloligand as precursor mixture interacts with
the second metal ions in a sequential manner.
In the current work, the synthesis of new metal-organic framework (MOF)
compounds by employing one-pot as well as sequential synthesis has been attempted.
The structures of the compounds have been determined by employing the single-crystal
X-ray diffraction technique. The prepared compounds possess both Lewis acidic and
basic centers, which were exploited for catalytic studies. The catalytically active sites
were employed to catalyze single-step as well as multiple-step reactions in a tandem
fashion. Some of the compounds exhibit water adsorption and proton conductivity
behavior. In addition, the thermochromic behavior of the framework compounds has
been described in detail.
Chapter 1 presents a brief overview of metal-organic framework (MOF)

/Ag+
; H2mna = 2-mercaptonicotinic acid) and
Cd2+ are presented.
In chapter 3, the synthesis, structure, thermochromism and Lewis acid catalytic
behavior of [Cu6(2-mna)6]6-based heterometallic metal-organic framework compound
are presented.
In chapter 4, we present the synthesis, structure and Lewis acid-base catalytic
studies of 1,4-naphthalene dicarboxylic acid based metal-organic framework compounds.
In chapter 5, the synthesis, structure and one-pot tandem catalytic studies of bi functional metal-organic framework compounds are presented.
In chapter 6, the synthesis, structure and multi-step tandem catalytic studies of 3-
amino triazole based metal-organic framework compounds are presented. | en_US |
