Thermosoftening phenyl siloxane glasses prepared via sol concentration

Preparation and properties of europium-doped phosphosilicate glasses obtained by the sol–gel method

“…Many kinds of functional organic compounds which cannot be introduced into conventional low-melting glasses can be introduced into phenyl-modified polysiloxane glasses due to the higher affinity for the phenyl group of the siloxane. Another advantage is that these functional compounds can be introduced into phenyl-modified polysiloxane glass melts without thermal decomposition because of the possible low-temperature processing and molding [2,3].…”

Chemical Tailoring of Hybrid Sol−Gel Thick Coatings As Hosting Matrix for Functional Patterned Microstructures

“…In fact, functional organic compounds that usually cannot be introduced into conventional low-melting glasses can be introduced into phenyl modified polysiloxane glasses because of the high affinity for the phenyl group bonded to the siloxane network. 16 In this way, a chemical modification of fullerene is not needed to use its functional properties. 22 The hybrid films after processing are transparent and crack-free.…”

“…The proposed sol gel resist presents also further appealing features for the fabrication of customized optical devices. In fact, as presented in Figure , functional organic compounds that usually cannot be introduced into conventional low-melting glasses can be embedded into phenyl modified polysiloxane glasses due to the high affinity for the phenyl group bonded to the siloxane network . Therefore important functional polycyclic aromatic molecules for optical applications (anthracene, pentacene, and fullerene , ) can now be homogeneously dispersed and patterned for the fabrication of new devices.…”

Effect of Solvent and Catalyst Types on Stability and Properties of Zinc Phthalocyanine in the Organic–Inorganic Hybrid Materials

“…These kinds of materials have found applications in nonlinear optics (NLO) and as biosensors [13][14][15][16]. Due to the low thermal stability of organic compounds, the OI hybrids should be obtained by low thermal processes, i.e., a sol-gel method [17][18][19]. In the organically modified silicate matrix (ORMOSIL), the alkoxides are modified by organic groups (e.g., epoxy, amine, phenyl groups).…”

“…It results in significant improvement of the hydrophobic/hydrophilic character and diminishing porosity of the material. Conditions for conducting the sol-gel synthesis, i.e., mainly the kind of catalysts and pH values of sols, type of solvents, and molar ratio of precursors affect the rate of hydrolysis and condensation of precursors and gelation, and consequently change the structure, and finally, the optical properties of material [17][18][19][20][21][22].…”
