Background
Metal Organic Frameworks (MOFs) and Inorganic Nanocrystals (INC) are powerful materials that help to alleviate the energy crisis and solve environmental problems. Some examples of successful assembly of the complementary functions of MOF and INCS provide good reference for new material design, e.g., TiO grown in MIL-101 pores2NCs produce a novel catalyst that utilizes TiO2And MOF to promote photocatalytic reduction of CO2While generating O2。
However, self-assembly of MOF-INC with defined crystallographic orientation has not been completed. MOFs and INCs have different lattice parameters and synthesis methods. Since the self-assembly solution of colloidal particles is dominated by entropy and energy interactions, mixing different types of MOFs and INCS often results in uncontrolled phase separation. It is generally found that the INCs are incorporated into the pores of the MOF in a random orientation and not atomically coherent. This is an inherent limitation that severely limits the usefulness of MOF-INC in advanced applications.
To our knowledge, this is the first about obtaining inorganic nanoparticles (TiO) by ordered assembly2) And metal organic framework (PB) mesogenic composites. The method can overcome the assembly limitation specific to the nano particles, broadens the selection of the artificial construction of the ordered assembly material and improves the universality of the ordered assembly method.
