Diisocyanates as novel molecular binders for monolayer assembly of zeolite crystals on glassElectronic supplementary information (ESI) available: experimental details. See http://www.rsc.org/suppdata/cc/b2/b205046c/

Isocyanate groups readily form urethane linkages with surface hydroxy groups on glass and zeolites and this phenomenon was utilized in the assembly of monolayers of zeolite microcrystals on glass by employing diisocyanates as novel molecular binders.

Orientation-Controlled Monolayer Assembly of Zeolite Crystals on Glass Using Terephthaldicarboxaldehyde as a Covalent Linker

Abstract Glass plates and pseudo hexagonal prismatic ZSM-5 crystals tethered with 3-aminopropylsilyl (APS) groups, respectively, were prepared by treating them with 3-aminopropyltriethoxysilane. Subsequent treatment of the APS-tethering glass plates with terephthaldicarboxaldehyde led to facile assembly of benzaldehyde (BA) units over the glass plates via imine (–CH N–) linkages. When the BA-tethering glass plates and the APS-tethering zeolite crystals were allowed to contact in boiling toluene, the ZSM-5 crystals strongly adhered onto the glass plates in the form of closely packed monolayers with perfect one-dimensional orientation.
