Molecular recognitions by use of porphyrin derivatives as host molecules are reviewed. Following three subjects are discussed in detail;
i) molecular recognitions on the porphyrins by the various types of space designs for environments around axial ligands, ii) molecular recognitions of functional groups on guest molecules by use of specific interactions between porphyrin hosts and guest molecules, iii) chiral molecular recognitions via introduction of chiralities into porphyrin rings or their functional groups.
In these sections, it is shown that the variety of molecular recognitions including multiple cooperative interactions have been realized by use of porphyrin derivatives. The most characteristic advantage of porphyrins as host molecules is that the positions and orientations of the functional groups can be controlled so precisely as to optimize the interactions operating between the host-guest couples, because of their rigid structures.
