Porphyrins and related macrocycles provide an extremely versatile synthetic base for a variety of materials applications. The exploration of metallopoi-phyrin assemblies as building blocks for tailored materials properties has grown rapidly during the past decade. In this chapter, we shall review the rather diverse applications of porphyrins to materials chemistry and try to draw the common threads between these topics. 

In contra.st to their interaction with applied electric, magnetic or electromagnetic fields, porphyrins and metalloporphyrins can also interact with other chemical species. One might view such interactions as chemo-responsive rather than field-responsive. The development of chemo-responsive materials based on porphyrins, however, is somewhat less advanced. One example of such applications is that porphyrin solids, being highly porous, are involved in the current development of molecularly based molecular sieves or shape-selective solid catalysts. Porphyrins and metalloporphyrins have also been examined for a variety of sensor applications, further proving their importance as a class of chemo-responsive materials.
