(1) Supramolecular architectures formed by non-covalently
interacting guanosine derivatives are studied. The
self-assembly process that leads to these highly
organised structures is investigated, as well as
their possible applications as molecular
devices. (2) By dissolving a chiral non-racemic
molecule in a nematic liquid crystalline phase, a chiral
nematic is generated: characeristics of the induced
cholesteric (pitch and helical sense) give information on the
stereochemistry of the solute. (3) Photoresponsive molecules
are designed to be employed
as photochemical switches or chemosensors, possibly
incorporated in liquid crystals.
