Chemistry in Molecular Vessels
Properties of chemical entities in confined nanospace are expected to be different from their bulk properties due to restricted rotational and vibrational motions. Such restricted motions along with other interaction/s may allow to stabilize unusual conformations of compounds in confined space of molecular cavity. Moreover, reactivity and reaction pathways in confined space may become different from traditional bulk reactions leading to the formation of unusual product/s. In this regard, chemists have been trying to design artificial molecular vessels to perform chemical reactions in their confined nanospace. Design of 3D molecular architectures having hydrophobic confined space including their use for catalytic organic transformations will be discussed. The lecture will also focus on the interior decoration of nanocages with urea moieties for new generation discrete heterogeneous catalysts for Michael addition (Figure-1).1-7 It is also planned to focus on our recent work on the use of confined space of discrete organic cages for the nucleation of tiny palladium nanoparticles and their successful use in facile transformation of aryl halides to corresponding cyanides.
