“…The overall T g of semi-IPNs increased when compared to PEI membrane which may be due to the formation of the network structure. In a semi-IPN, the molecular motion of each polymer is further restricted due to entanglements between the components leading to a higher T g [26]. Also as discussed earlier, the bulky fluoroenyl group imparts rigidity to the system, which might also increase the T g [16].…”

“…The encapsulated alkoxysilane dye undergoes hydrolysis and condensation during the polymerization of the polymer to produce a highly crosslinked, intertwined network with reduced polymer motions. Tripathy and coworkers have obtained excellent results using this approach [39][40][41]50]. In one study, the alkoxysilane dye (Fig.…”

“…Indeed, most of the recent focus on the preparation of NLO materials via the sol-gel route have involved the ORMOSILs [36]. The research groups of Tripathy [37][38][39][40][41], Chaput [42,43], Plawsky [44,45], Sanchez [46], and Dalton [47][48] have been key investigators in this developing field.…”

Abstract. Inorganic-organic hybrid materials prepared by the sol-gel process have become an attractive field of study due to the immense versatility associated with this method of composite material preparation. The blending of inorganic precursors with organosilicon reagents enables unique materials to be fabricated with the desired chemical and physical characteristics. The ability to control the interfacial polarity, the degree of porosity, and the chemical functionality in the matrix has been shown to be a powerful tool in the design of materials for sensor, optical, chromatographic, and catalytic applications. In this review, the preparation of the organically modified silicates (ORMOSILs) where the individual precursors are covalently bound to each other is discussed and selected examples of their potential usefulness in analytical applications is presented.

“…Inorganic matrix based guest/host systems have been developed in our laboratory as well as by others [15][16][17][18][19][20]. The unique feature of our approach is using a low molecular weight inorganic polymer(oligomer) as a precursor to the network in addition to following the conventional technique using monomers such as tetramethoxysilane and tetraethoxysilane [18][19][20].…”

“…In this section we report on a scheme that allows the sol-gel reaction to take place in a high Tg polymer matrix. The high Tg of the polymer along with the sol-gel inorganic network would be expected to stabilize the aligned NLO chromophores by decreasing their mobility [16].…”
