This Account summarizes various methods of organizing zeolite microcrystals into two-dimensional functional entities such as monolayers, multilayers, and patterned monolayers on various substrates and three-dimensional functional entities such as microballs and protein-zeolite composite fibrils. In the case of monolayer assembly, various types of linkages and substrates, factors that govern the rate, degree of coverage, degree of close packing, degree of uniform orientation, and average binding strength between each crystal and the substrate are described. The current and future applications of the organized products are also discussed.

“…However, despite a large progress made during the last several decades in the synthesis of new zeolites and the related molecular sieves [15], there have been no synthetic methods for production of uniformly aligned zeolite multi-crystal arrays. We have explored a possible post synthetic route to the production of ordered multicrystal arrays of zeolite on substrates through organization of preformed zeolite crystals with well-defined chemical linkages [16][17][18][19][20][21][22][23][24][25][26][27]. Although the above route has shown great potential, it has not yet shown the ability to control the orientation of zeolite crystals with respect to the [28][29][30][31] and the phenomenon that polyurethane sponges serve as templates for facile synthesis of large, self-supporting silicalite foams [32], we have recently demonstrated that the polyurethane films with uniformly aligned backbones can serve as the matrices for production of uniformly aligned 2D and possibly 3D arrays of zeolite crystals with uniform orientations and the nature of the polymer determines the orientation [33].…”

Two types of glass plates coated with uniformly aligned polyurethane films were produced by repeating the cycles of the alternative exposures of the glass plates to 1,4-phenylene diisocyanate (PDI) and 2-butyne-1,4-diol (BDO) and to PDI and terephthalic acid bis-(2-hydroxy ethyl) ester (TBE) for 500 times at elevated temperatures. The glass plates coated with uniformly aligned poly-(PDI-BDO) 500 (500 represents the number of the cycle) produced monolayers of closely packed 2D arrays of silicalite-1 crystals with the average size of 370 × 200 × 500 nm on the glass plates upon immersion of the glass plates into a dense gel consisting of tetraethylorthosilicate (TEOS), tetrapropylammonium hydroxide (TPA + OH − ), and water (mole ratio = 7:1.5:330) followed by the hydrothermal reaction at 180 °C for 2 h. The silicalite-1 crystals were aligned with the c-axes perpendicular to the substrate plane. Upon switching the polymer from poly-(PDI-BDO) 500 to poly-(PDI-TBE) 500 the orientations of the silicalite-1 crystals in the 2D arrays changed from c to a axes perpendicular to the substrate. This report therefore demonstrates that the uniformly aligned polyurethane films serve as the templates for the growth of closely packed multi-crystal arrays of silicalite-1 in uniform orientations and the nature of the polyurethane film affects the resulting orientations of the crystals. We propose that the supramolecularly organized organic-inorganic composites consisting of the hydrolyzed organic products and the seed crystals responsible for the above phenomena.

“…In earlier reports for selective deposition, 6,[8][9][10][11][12][13][14][15] it has been shown that patterned SAMs of OTS, can be utilized as molecular resists to create micrometer scale patterns of organosilane monolayers on the substrates for directing the deposition of thin-films. Patterned metal thin-films of Cu, 8,9 Pt, 10 3 13 has been carried out by sol-gel method.…”

“…We have also shown that patterned OTS SAMs formed by the µCP can be combined with the chemical solution deposition (CSD) for the micro-patterning of CdS thin film 14 and of zeolite particles. 15 OTS SAMs are used in these works to functionalize surfaces with organic thin films, thereby influencing the strength of the interactions of the substrate with reagents used in the sol-gel deposition process.…”

The micro-patterning of multi-layered thin films containing CdS and Ta 2 O 5 layers on ITO substrate with various structures was successfully obtained by combining three different techniques: chemical solution depositions, sol-gel, and microcontact printing (µCP) methods using octadecyltrichlorosilane (OTS) as the organic thin layer template. Ta 2 O 5 layer was prepared by sol-gel casting and CdS one obtained by chemical solution deposition, respectively. Parallel and cross patterns of multi-layers with Ta 2 O 5 and CdS films were fabricated additively by successive removal of OTS layer pre-formed. This study presents the designed architectures consisting of the two types of feature having horizontal dimensions of 170 µm and 340 µm with constant thickness ca. 150 nm of each deposited materials. The thin film lay-out of the cross-patterning is composed of four regions with chemically different layer compositions, which are confirmed by Auger electron microanalysis.
