Metal-organic Frameworks (MOFs) are a new class of porous material with enormous potential for several technological applications. Recently, the growth of such structures on functionalized surfaces, called Surface-supported Metal-organic Frameworks (SURMOFs), has provided the possibility to design new applications in strategic fields such as electronics, optoelectronics and energy. However, the growth with high crystallinity degree and considerable control in thickness is still a critical and relevant challenge in scientific and technological scenario. In this way, this proposal aims not only to optimize these growth parameters on functionalized surfaces, but also their electrical properties and applications in memristors, hybrid capacitors and sensors. Initially, the growth of SURMOFs (HKUST-1 and MOF-5) on different functionalized surfaces (metallic and Al2O3) will be studied considering their structural and morphological characteristics as a function of deposition parameters and doping of foreign molecules, such as ferrocene. The growth will be performed using Layer-by-Layer (LbL) technique with Liquid-phase Epitaxy (LPE). The electrical properties and applications in electronic devices will be explored using self-rolling technology obtained by microfabrication techniques. This technology presents as main advantages the considerable reduction of footprint area, the capability of preparing electrical contacts on sensitive nanomaterials and the possibility of devices association in series. Therefore, the originality of this proposal is highlighted, particularly considering the application of SURMOFs in memristors and sensors using self-rolling technology.
