Abstract:

The photoreversible color switching system (PCSS) is attracting increasing attention for use in alleviating energy crisis and environmental problems. We report a robust PCSS in which lattice matching enables bottom-up oriented assembly between metal-organic frameworks (MOFs) and inorganic nanocrystals (INCs), two distinct entities that differ drastically in structure and function. Specifically, cubic-phase Prussian blue (PB) of a framework backbone is spontaneously attached to rutile TiO2 nanowires in a defined orientation triggered by the lattice matching between the (001) plane of TiO2 and the (222) plane of PB. Ultraviolet light irradiation accelerates the photoelectron transport within the oriented TiO2/PB system and enables fast photo switching. The derived TiO2/PB paper can be ranked as one of the best light-printing papers in literature because of its high resolution (∼ µm) and capability to be repeatedly written for >100 times without significant loss of contrast. The ultrathin TiO2 nanowires are rich in oxygen and Ti vacancies, which allow visible- and sunlight-light printing. Density functional theory calculations suggest that the [Fe(CN)6]4− ligand from the PB attaches preferentially to the (110) surface of TiO2 to give the ordered TiO2/PB assembly. The findings demonstrate the strong versatility of particles-mediated assembly in advanced materials design. © 2021, Science China Press and Springer-Verlag GmbH Germany, part of Springer Nature.
