报告摘要:

Metal-Organic Framewoks, MOFs, offer unique opportunities to integrate physico-chemical properties and functionalities by the choice and the design of the building blocks, such as metal nodes, organic linkers, hosted guests by the tailoring of their spatial arrangement, i.e. via reticular synthesis. The lecture will focus on photoactive MOFs which are characterized by using chromophores as linkers. Four case-studies will be presented and discussed (Figure): (1) Photocatalytic CO₂-to-syngas evolution with dual molecular catalyst loaded NU-1000, that features a pyrene-chromophore.¹ It delivers energy efficiently to the active sites, conceptually yielding a nanozyme function with benchmark turnover numbers and record incident photon conversions up to 36%. (2) Decoupled solar energy storage and dark photocatalysis in 3D MOFs.² The embedding of Mn and Re redox centers in the confined space of the photoactive framework unlocks a unique electron accumulating property under visible-light irradiation. About 15 C g_MOF⁻¹ of electric charges can be concentrated and stored for over weeks. (3) Photochromic MOFs, functionalized with spiropyranes, feature stimulus-adaptable performance and demonstrate the ability to shift between multiple relaxation pathways as a function of the excitation wavelength. It resulted in photoswitch-directed tailoring of model phosphinylation reaction outcomes.³ Finally, (4) the tailoring and optimization of the multiphoton-absorption efficiency by MOF crystal engineering involves subtle interaction phenomena induced by pyrene, carbazole and perylene diimide chromophore packing, conformational strain and rigidification.⁴ The examples will be put into the wider perspective of the development of multifunctional photoactive porous network materials.
