NOTE A Pyrene-Loaded Film Composed of Triton X-100 and Poly(vinylmethylether) atmosphere, i.e., in the absence of oxygen [cf. (5)], compared to the time measured in air. A thin uniform transparent film composed of the nonionic sur-The dynamic properties of a Triton film can be largely modified if a factant Triton X-100 and of poly(vinylmethylether), MW Γ polymer is cosolubilized.

In this type of complex film we have added a well-known fluorophore, the temperature. The pyrene-loaded film can be used as an optical pyrene, and have studied its excimer formation. Pyrene was previously oxygen sensor.
