ABSTRACT:
Compounds are disclosed which comprise parallel, multiring, porphyrin-related compounds, particularly two-ring phthalocyanine compounds, which have a coordinating atom, either a metal or a metalloid, located at their center. The coordinating atoms in adjacent rings are connected by an oxygen bridge along an axial backbone disposed at right angles to the rings, and the coordinating atom and the ring on one end of the axis has a hydrophilic group attached thereto, while the coordinating atom in the ring at the other end of the axis has a hydrophobic group attached to it. Semiconducting films made from such compounds and devices made from such films, especially gas sensors, are also disclosed.
