Víctor Rubios work has just been accepted in Advanced Materials. This paper reports on the convenience of a solution-based bottom-up method, which combines the use of the Langmuir-Blodgett technique, Layer-by-Layer and self-assembled monolayers to transfer high-quality ultrathin films of a semiconductive 2D MOF in a controlled fashion. This versatile methodology enabled us to fabricate MOF-based electronic devices and study the electrical conductivity on the thinnest MOF films (10 nm thick) reported so far. For more info see here
