Paper Abstract

Monomolecular thin solid films containing water-soluble Pt- and Pd-porphyrins were prepared and transferred onto solid supports. Surface active charged polymer on the basis of alkylated polyethyleneimine was used to improve extraction of the dye from aqueous solution to the interface. The solid-state materials obtained which showed intense long-decay luminescence were studied by optical methods with emphasis to luminescence quenching and lifetime measurements. The results were applied to quenched-luminescence lifetime-based sensing of relative air humidity. A corresponding fiber-optic prototype device was developed.
