Abstract
In current nanotechnology, bottom-up approaches where supramolecular chemistry plays a crucial role are gradually gaining in importance relative to the top-down approaches. A key process of the bottom-up approaches is self-assembly of component materials where supramolecular chemistry plays a crucial role. Well-designed structures formed through self-assembly particularly make excellent prototypes for functioning man-made devices. Recent advances in organic chemistry allow us to construct attractive units that can be assembled into further advanced micro-factories, leading to switchable properties and dynamic functions. In this review, supramolecular approaches in nanotechnology for developing switching properties and dynamic functions are summarized and classified into three categories: (i) molecular functions in solution; (ii) hard supramolecular systems; (iii) soft supramolecular systems.
Keywords: Supramolecular chemistry, self-assembly, organic-inorganic hybrid, molecular machine, surface chemistry, Nanotechnology, Dynamic Functions, cellular phones, hydrogen bonding., characteristics, transportation systems., microfabrication methods, Solution, Artificial enzyme, sexithiophene-based

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
