Nanoscale alignment of 1D polymers
For the segregation of polymers in individual chains and the controlled alignment of conjugated polymers, we here introduce two different approaches where one is to utilize a crosslinking molecule ("aligner") and the other is to use a twining polymer ("twimer") for organizing conjugated polymers.
Rational design of supramolecular assemblies comprised from
Pai-conjugated molecules.
Exploring a general principle to control the morphology and the electronic state of pai-conjugated molecule-based assemblies has been the most important research target in supramolecular chemistry, which leads to the creation of various functional materials with optimized pai-electronic properties. We demonstrated that achiral porphyrin derivatives form twisted supramolecular assemblies and the helical pitch is controllable by changing the strength of porphyrin-porphyrin p-p stacking by the central metal.
Rational design of chemosensors and dynamic molecular recognition system utilizing allosterism.
Unconventional enantioselective recognition
by an error-filtering system
The remarkable embodiment that appropriate covalent linking of receptor
sites arranged around rotational axis could lead to both high selectivity
and high molecular recognition came with our introduction of artificial allosteric
recognition systems based on bis[porphyrinato]cerium(IV) double decker complexes.
