In this laboratory, dendrimers are constructed relying on the experience gained in previous research on azides, heterocumulenes, heterocyclic rings and 1,3-dipolar cycloadditions. Rotaxanes and catenanes consist of two or more molecules which are linked in a non-covalent manner. The rotaxanes have one or more cyclic molecules trapped on a dumbbell-shaped unit. Catenanes consist of two or more rings which are interlocked. Again, several supramolecular dynamic processes can occur.
Porphyrins are cyclic tetrapyrroles of tremendous importance in biology and chemistry.
Modified porphyrins are being investigated, with functionalisations either on the pyrrole rings or the meso positions, to influence the properties of these compounds. Soc., Perkin Trans.
