This research is being supported by the Organic and Macro-                      molecular Chemistry Program.  The molecules utilized by                         living systems have evolved over billions of years.  Thus the                   porphyrin and corrin families of structures are crucial to the                  catalytic properties in vitamin B-12, cytochrome C-450,                         hemoglobin and chlorophyll among others.  This research will                    look into a structural type which will permit some of these                     systems to be mimicked.                                                                                                                                         This research will synthesize the pyridino analog of the                        porphyrin system in which the pyrrole rings will be                             systematically replaced by the pyridino functionality.  This                    will result in quadridentate macrocycles possessing electron-                   poor rings which should have many novel electronic and                          coordination properties.  The properties of the corresponding                   tridentate systems will also be examined.  The work should 1)                   develop new synthetic paths into these systems; 2) chemical                     modification of the "meso" bridges; 3) studies of the physical                  properties of these systems; and 4) study of the metal                          complexes and their possible stacking interactions.
