Накратко на български

Метал-органичните рамки (MOF) с добавени светещи вещества се изследват чрез нов метод на нанасяне чрез изпарение за създаване на тънки филми. Това помага за разработването на по-стабилни бели светодиоди и сензори за летливи органични съединения, съвместими с микроелектрониката.

Vapour phase deposition of metal-organic frameworks with luminescent guests for solid-state lighting and sensing

Metal-organic frameworks (MOFs) are solid compounds consisting of metal ions or clusters coordinated to organic ligands to form one-, two-, or three-dimensional structures. MOF materials possess unique advantages for luminescence-based applications primarily because of their capability of incorporating luminescent guests at both metal centers and organic ligands. This allows efficient modulation of luminescent properties. In addition, permanent porosity in these structures permits the accommodation of luminescent guests (LGs) within their frameworks, offering another degree of tunability in their emission properties. Because of the well-defined nano-environments in their pores, MOFs have high potential as encapsulation matrices to enhance both the efficiency and stability of LGs. For many applications, especially in (micro)electronics, a key enabling step in leveraging the properties of MOFs will be the development of robust thin film deposition methods. However, all reported thin-film fabrication techniques is solution based, which is incompatible with microelectronic fabrication processes because of contamination and corrosion upon exposure to the MOF synthesis mixture and the environmental impact and cost related to solvent use. The recently developed vapor phase deposition technique for MOF film deposition (MOF-CVD) has shown great advantages for the fabrication of uniform MOF thin films. However, it was only demonstrated as a proof-of-concept, for the MOF material ZIF-8. In the VAPOMOF project, we will broaden the scope of MOF-CVD and implement it for the fabrication of LG@MOF thin films for development of phosphor-converted white light-emitting diodes (PC-WLED) and volatile organic compounds (VOSs) sensors. This general objective translates in a set of specific partial objectives: 1) Broadening the scope of MOF-CVD; 2) Fabrication of LG@MOF films through MOF-CVD; 3) PC-WLED based on LG@MOF layers deposited though MOF-CVD; 4) Optical sensing of small VOCs via responsive LG@MOF films deposited through MOF-CVD.

Цел на проекта

Metal-organic frameworks (MOFs) are crystalline solids with highly regular pores in the nanometre range. Because of their unique properties, MOFs are high-potential candidates for integration with microelectronics. However, current methods for MOF film deposition, a key enabling step in device integration, are incompatible with microelectronics fabrication because of contamination and corrosion issues.The VAPOMOF host group very recently demonstrated the deposition of MOFs via chemical vapour deposition (CVD). This MOF-CVD technique circumvents the above issues and opens up a plethora of opportunities for MOF integration because of compatibility with existing microelectronics fabrication infrastructure.VAPOMOF targets the expansion of the MOF-CVD platform is and its implementation in two application areas:(1) MOF-CVD coatings with encapsulated luminescent guests to enable more efficient and affordable white-light emitting diodes.(2) MOF-CVD coatings with encapsulated responsive luminescent guests for the detection of volatile organic compounds via a change in the emission properties.The combined expertise of the fellow and host ensures the best chance for successfully completing the VAPOMOF objectives in a mutually beneficial manner. In addition, a secondment at a world-leading research centre with close ties to the microelectronics industry will provide insights in industrial needs and standards and a view on valorisation of scientific research.
