“…Synthesis of c-axis-oriented 1D-channel zeolite monolayers or arrays with the channels open at the off-substrate ends and ready to load dye molecules has been of particular interest and intensively investigated [4]. To seal the entrance(s) to the 1D channels in case of dye molecule leakage after loading, stuffing at the end(s) of the 1D channels with molecules (phthalocyanine, for instance) serving as stopcock or surface coating is often performed [5].…”

“…A typical process to obtain 1D-channel zeolite thin films with well-aligned grains by first loading a seeding layer on the substrate followed by the further epitaxial growth has been described as follows by Xue et al [4]: first by surface modification of the quartz slice substrate using cation polymer, for example, poly(diallyldimethylammonium chloride) (PDDA), to get a positively charged substrate surface as template for the zeolite seed crystals; then seeds loading via immersing the substrate horizontally in the seed crystals suspension, followed by rinsing and drying to get the seeds slice; growth of the c-axis-oriented AFI film by a further hydrothermal crystallization in the autoclave; organic template (PDDA) removal by calcinations; and finally dye molecules loading by adding the calcined c-axis-oriented AFI thin film in an azo dye molecule (DPPA) solution. This azo dye molecule containing c-axis-oriented AFI zeolite film shows ability for detecting heavy metal ions by monitoring the optical absorption variation, particularly efficient for the detection of Zn 2+ ions.…”

Compared with the intensive fundamental research and practical application development of zeolites in the fields of photocatalysis, separation, ion exchange, and antimicrobial, research on the luminescence from optically functionalized zeolites is still at a juvenile stage. So far, plenty of important potential applications based on luminescent zeolites, such as light harvesting, phosphors, optical encoding/recording, micro-lasers, chemical sensors, and bio-imaging, have been demonstrated. What's more, it has been shown that the porous crystalline nature of zeolites makes them an excellent matrix for investigating the fundamental physics of the sub-nm-scale luminescent metal clusters, which is still not sufficiently clear till now. Due to its significance, luminescent zeolites functionalized by luminescence-active guest species in various types including organic dye molecules, rare earth (RE) ions, bismuth ions, and d 10 metal ions are reviewed in this chapter, dedicating to presenting some representative work on luminescent zeolites during the past few decades, from materials design, preparation, to application demonstrations, in hope to boost more research interest and strength in this community.To date, optically activated luminescent zeolites are mainly focused on several types of aluminosilicate zeolites with the dimension of pores or channels in the scale of about 0.3-1.5 nm, such as the FAU-type, the LTL-type, the LTA-type, the ZSM-5-type, and the SOD-type zeolites. Here, in this chapter, the zeolites mainly refer to these nanoporous zeolites functionalized by luminescent centers.

Vorliebe für Krebszellen: Zeolith‐L‐Nanokristalle wurden enantioselekiv funktionalisiert und als enantiomorphe selbstorganisierte Monoschichten (SAMs) angeordnet. Das Adhäsionsverhalten verschiedener Zellen an diesen neuen Biomaterialien wurde bezüglich der Chiralität der entsprechenden Oberfläche untersucht. Dieses Konzept wurde zur Trennung von Primärzellen von Zelllinien angewendet (siehe Schema).

An emerging approach to improve the physicobiochemical properties and the multifunctionality of biomaterials is to incorporate functional nanomaterials (NMs) onto 2D surfaces and into 3D hydrogel networks. This approach is starting to generate promising advanced functional materials such as self‐assembled monolayers (SAMs) and nanocomposite (NC) hydrogels of NMs with remarkable properties and tailored functionalities that are beneficial for a variety of biomedical applications, including tissue engineering, drug delivery, and developing biosensors. A wide range of NMs, such as carbon‐, metal‐, and silica‐based NMs, can be integrated into 2D and 3D biomaterial formulations due to their unique characteristics, such as magnetic properties, electrical properties, stimuli responsiveness, hydrophobicity/hydrophilicity, and chemical composition. The highly ordered nano‐ or microscale assemblies of NMs on surfaces alter the original properties of the NMs and add enhanced and/or synergetic and novel features to the final SAMs of the NM constructs. Furthermore, the incorporation of NMs into polymeric hydrogel networks reinforces the (soft) polymer matrix such that the formed NC hydrogels show extraordinary mechanical properties with superior biological properties.
