第104回 アイセムスセミナー: Prof. Dr. Christof Wöll
The fabrication of surface-anchored, crystalline, highly porous metal-organic frameworks (MOFs) on solid substrates using liquid-phase epitaxy (LPE) [1] opens the way to interesting applications in the area of sensorics, enantiomer separation, heterogeneous catalysis and electrochemistry [2]. We will demonstrate the LPE- principle for the case of [Cu3(BTC)2]n (HKUST-1) grown on COOH- and OH-terminated self-assembled monolayers (SAMs). SPR (surface plasmon resonance) spectroscopy has been used to monitor the growth in-situ [3]. XRD data reveal the formation of highly ordered, oriented crystalline MOF thin films with a structure identical to that observed in the bulk [4]. Recent results on electrochemical properties of SURMOFs will be discussed [5].
