showed high electric mobility at room temperature. In 2020 the same material was integrated in a photo-detecting device, detecting a broad wavelength range from UV to NIR (400–1575 nm). This was the first time a two-dimensional semiconducting MOF was demonstrated to be used in opto-electronic devices. Cu3(HHTP)2as a 2D MOF structure, and there are limited examples of materials which are intrinsically conductive, porous, and crystalline. Layered 2D MOFs have porous crystalline structure showing electrical conductivity. These materials are constructed from trigonal linker molecules (phenylene or triphenylen) and six functional groups of –OH, -NH2, or –SH. The trigonal linker molecules and square-planarly coordinated metal ions such as Cu^{2+},Ni^{2+}, Co^{2+}, and Pt^{2+} form layers with hexagonal structures which looks like Graphene in larger scale. Stacking of these layers in the c direction shown in Figure 6 can build one-dimensional pore system. Graphene-like 2D MOFs have shown decent conductivities. This makes them a good choice to be tested as electrode material for evolution of hydrogen from water, oxygen reduction reactions, supercapacitors, and sensing of volatile organic compounds (VOCs). Among these MOFs, Cu3(HHTP)2 has exhibited the lowest conductivity, but also the strongest reaction in sensing of VOCs. Bio-mimetic mineralization Biomolecules can be incorporated during the MOF crystallization process. Biomolecules including proteins, DNA and antibodies could be encapsulated within ZIF-8. Enzymes encapsulated in this way were stable and active even after being exposed to harsh conditions (e.g. aggressive solvents and high temperature). ZIF-8, MIL-88A, HKUST-1, and several luminescent MOFs containing lanthanide metals were used for the biomimetic mineralization process. Carbon capture Adsorbent MOF's small, tunable pore sizes and high void fractions are promising as an adsorbent to capture CO2. MOFs could provide a more efficient alternative to traditional amine solvent-based methods in CO2 capture from coal-fired power plants. MOFs could be employed in each of the main three carbon capture configurations for coal-fired power plants: pre-combustion, post-combustion, and oxy-combustion. The post-combustion configuration is the only one that can be retrofitted to existing plants, drawing the most interest and research. The flue gas would be fed through a MOF in a packed-bed reactor setup. Flue gas is generally 40 to 60 °C with a partial pressure of CO2 at 0.13 - 0.16 bar. CO2 can bind to the MOF surface through either physisorption (via Van der Waals interactions) or chemisorption (via covalent bond formation). Once the MOF is saturated, the CO2 is extracted from the MOF
