Photon Up-Conversion via Epitaxial Surface-Supported Metal–Organic Framework Thin Films with Enhanced Photocurrent

Photon Up-Conversion via Epitaxial Surface-Supported Metal–Organic Framework Thin Films with Enhanced Photocurrent

We report a new triplet–triplet annihilation photon up-conversion (TTA-UC) system using an epitaxial Zn-perylene surface-supported metal–organic framework (SURMOF) grown on metal oxide surface as “emitter”, and a platinum octaethylporphyrin (PtOEP) as “sensitizer” in [Co­(bpy)3]2+/3+ acetonitrile so...

Zusammenfassung:We report a new triplet–triplet annihilation photon up-conversion (TTA-UC) system using an epitaxial Zn-perylene surface-supported metal–organic framework (SURMOF) grown on metal oxide surface as “emitter”, and a platinum octaethylporphyrin (PtOEP) as “sensitizer” in [Co­(bpy)3]2+/3+ acetonitrile solution. It has been demonstrated that the photocurrent can be significantly enhanced relative to epitaxial Zn-perylene SURMOF due to the TTA-UC mechanism. This initial result holds promising applications toward SURMOF-based solar energy conversion devices.
