| Abstract
| - We describe the complete synthesis and characterization of a new family of peripherally functionalizedporphyrazines (pz's) with four, three, or two (in a trans conformation) bis[thioethoxy(ethoxy)ethanol] moietiesappended at the pyrroles. These “polyetherol” groups serve as weak exocyclic binding sites for a number ofmetal ions and also provide solubility of the pz's in low molecular-weight alcohols and water. Electronic spectraof the modified porphyrazines exhibit distinct changes in the visible region (both absorbance and fluorescence)in response to treatment with Ag+, Pb2+, Cd2+, Cs+, and Ni2+ in solution. Such properties make these compoundsintriguing candidates for incorporation into the transducer layers in optically based chemical sensors.
- A new familiy of pophyrazines containing four, three, or two (in a trans configuration) bis[thioethoxy(ethoxy)ethanol] groups appended directly to the periphery of the macrocycle has been prepared, and the changes in their optical and emission spectra in response to a variety of metal ions were investigated.
