A rotaxane exciplex.
The creation of molecular-scale photonic devices requires supramolecular logic elements.1-3 Although the study of supramolecular photochemistry is still in its infancy, it is clear that it offers much greater diversity than single-molecule systems. These components may permit access to complex photophysical processes, such as vectorial energy transfer, energy migration, and optical switching.4 ...
متن کاملPhotogeneration of Gelatinous Networks from Pre-Existing Polymers
In this manuscript we report the crosslinking of pre-existing macromolecules in solution through the use of photoactive benzophenone chromophores. We show that a bifunctional crosslinker composed of two benzophenone chromophores as well as a single benzophenone chromophore crosslink poly (butadiene) and poly (ethylene oxide) in solution to form insoluble gels when irradiated with UV light. The ...

متن کاملA bio-hybrid rotaxane catalyst
In processive catalysis, a catalyst binds to a substrate and remains bound while performing several consecutive reactions, as exemplified by DNA polymerases. Processivity is essential in Nature, and is often mediated by a clamp-like structure that physically tethers the catalyst to its (polymeric) template. In the case of the bacteriophage T4 replisome, a dedicated clamp protein acts as a proce...
متن کاملA double-stranded DNA rotaxane.
Mechanically interlocked molecules such as rotaxanes and catenanes have potential as components of molecular machinery. Rotaxanes consist of a dumb-bell-shaped molecule encircled by a macrocycle that can move unhindered along the axle, trapped by bulky stoppers. Previously, rotaxanes have been made from a variety of molecules, but not from DNA. Here, we report the design, assembly and character...
