| Abstract: | meso-Bromoporphyrins can be conveniently substituted by primary and secondary amines in a metal catalyst-free reaction which gives access to a large variety of meso-N-substituted derivatives. In some cases, considerable acceleration of this amination can be effected under microwave irradiation. The amino anchor on the porphyrin skeleton is useful for constructing novel self-assembling porphyrinoids as demonstrated by a single crystal X-ray analysis as well as stationary absorption and fluorescence spectroscopies. |
