文摘

The visible absorption spectra of various substituted porphyrin compounds both in chloroform solution andas Langmuir-Blodgett (LB) solid-state films have been investigated. The porphyrin compounds examinedwere the Zn, Sn, Mg, and free base derivatives of 5,10,15,20-tetrakis[3,4-bis(2-ethylhexyloxy)phenyl]-21H,23H-porphine (EHO). Changes in the absorption spectra of these materials induced by their exposure tovarious organic compounds are reported with a view toward determining whether this is a useful approachtoward an optical gas sensor.
