In this general lecture, we will take a glance at the recent developments in the electrochemical synthesis and deposition of the metal-organic framework thin films (MOFTFs). MOFs that have been introduced owing to the untiring endeavors of Yaghi and co-workers on the science frontier and followed by BASF in the industrial area are attractive materials for the modification of electrode, membrane and transducer surfaces. Although the MOFs have been known as green materials for sustainable goals, the eco-friendly synthesis of them as thin layer films are still challenging and open discussion. Tunable porosity, large surface area, catalytic effect, and structural diversity are prominent, but on the other hand, fragility and brittle or insolubility of most bulk MOF crystals are deficiencies of these compounds for modification of surfaces. To overcome these drawbacks, considerable scientific efforts were devoted to stabilization of MOFs as thin films. From a comprehensive perspective, two general categories can be mentioned; ex-situ and in-situ techniques. The former methods need to transfer of synthesized MOFs onto the substrate and therefore are less acceptable than the in-situ, or direct growth/deposition techniques with an intergrowth and integrated thin films. Meanwhile, electrochemistry is still a niche and unique platform to address the interfacing issue of MOFs with the underlying surface. This positive glance comes from the mild, one-step, selective and controllable strategy that would lead to the simultaneous synthesis and deposition of uniform films. Among the electrochemistry approaches that have been dedicated toward the in-situ/direct modification, anodic and cathodic techniques for microporous and mesoporous MOFTFs are easy on the eyes. In the anodic method that electrode plays the role of cation source, non-blocking of pores by salt and controlling of metal oxidation state are its beneficial features. However, restriction on the anode material selection an
