Intermolecular Interactions as Driving Force of Increasing Multiphoton Absorption in a Perylene Diimide‐Based Coordination Polymer

Advanced Functional Materials, EarlyView.
This study uncovers the unexplored role of intermolecular interactions in multiphoton absorption in coordination polymers. By analyzing [Zn2tpda(DMA)2(DMF)0.3], it shows how the electronic coupling of the chromophores and confinement in the MOF enhance two‐and three‐photon absorption.

Intramolecular Down‐ and Up‐Conversion in Dimeric Tetracene Complexes Centered via Platinum(II) and Palladium(II)

Advanced Functional Materials, EarlyView.
Metal‐tetracene dimeric complexes are synthesized through the pyridyl coordination to either Pt(II) or Pd(II). Photophysical properties are systematically compared as a function of the metal using steady‐state and time‐resolved spectroscopy. The Pt(II) dimer exhibits efficient intramolecular singlet fission and subsequent intramolecular up‐conversion ...
