“…Porphyrins and phthalocyanines have been applied to the detection of volatile, aromatic hydrocarbons previously [ 1 – 8 ]. Strong π-π*-interactions between the indicator macrocycle ( Figure 1 ) and the target provide the potential for large changes in the spectrophotometric characteristics of the porphyrin (or phthalocyanine).…”

The development of porphyrin-embedded mesoporous organosilicate materials for application to the detection of volatile hydrocarbon solvents is described. Design of the receptor and optical indicator construct begins with parallel selection of the porphyrin indicator and design of the mesoporous sorbent. For the porphyrin indicator, high binding affinity and strong changes in spectrophotometric character upon target interaction are desired. The sorbent should provide high target binding capacity and rapid binding kinetics. A number of porphyrin/metalloporphyrin variants and organosilicate sorbents were evaluated to determine the characteristics of their interaction with the targets, benzene, toluene, and hexane. The selected porphyrin candidates were covalently immobilized within a benzene-bridged sorbent. This construct was applied to the detection of targets using both fluorescence- and reflectance-based protocols. The use of red, green, and blue (RGB) color values from the constructs in a highly simplified detection scheme is described.

“…Porphyrins are versatile molecules, whose physicochemical properties are very sensitive to the modification of their electronic distribution on the aromatic ring [1,7,8,9]. This makes them excellent building blocks, which can create supramolecular architectures with very good spectroscopic properties [2,10].…”

“…Precursores de uma série de materiais tais como fibras, filmes finos e vidros podem ser preparados utilizando-se esta técnica. Em especial, filmes finos têm atraído a atenção devido à formação de poros em sua estrutura, os quais podem originar sensores químicos e membranas seletivas [1][2][3] . A preparação de óxidos através do processo sol-gel é baseada em reações de polimerização inorgânicas de alcóxidos de diferentes metais [4][5][6][7] .…”

Recebido em 21/8/02; aceito em 26/2/03 TITANIUM-SILICON FILMS PREPARED BY SPIN AND DIP-COATING. The conditions for the preparation of luminescent materials, consisting of Eu 3+ ions entrapped in a titanium matrix, in the forma of a thin film, using the sol-gel process, are described. The films were obtained from sols prepared with TEOS and TEOT, in the presence of acetylacetone as the hidrolysis-retarding agent, using the dip-coating and spin-coating techniques. The influence of these techniques on the films based on titanium and silicon are presented. The Eu 3+ was used as a luminescent probe. The films have been characterized by luminescence, reflection and transmittance. The thickness of the films could be related to the preparation procedure. Transparent thin films have been prepared by dip-coating technique.
