Cooperativity of Electron Transfer Coupled Spin Transitions in a Tetranuclear Fe/Co Prussian Blue Analogue Revealed by Ultrafast Spectroscopy

Angewandte Chemie, EarlyView.
Ultrafast pump‐probe spectroscopies show that irradiation of a square Fe/Co Prussian blue analogue induces electron transfer within one Fe–Co subunit followed by fast spin crossover, and coupled equilibria between all states trigger a second electron transfer coupled to spin crossover in the other Fe–Co subunit on a ns timescale.

Harnessing Negative Photochromism in Styryl Cyanines for Light‐Modulated Proton Transport

Angewandte Chemie, EarlyView.
We show how photo switchable styryl cyanines undergo an extremely efficient photochemical ring‐closing reaction upon irradiation. Furthermore, substituents on the ring and the nature of their surroundings can be used to tune their chemistry, kinetics, and photochemical properties. Finally, we demonstrate how these molecules can be used as smart dopants

Giant Birefringence Enabled by the Highly Anisotropic Linear IX2− (X = Cl, Br) Building Blocks

Angewandte Chemie, EarlyView.
Four novel, easily grown birefringent crystals featuring linear interhalogen birefringence‐active groups, IX₂⁻ (X = Cl, Br), namely [H‐4AP][ICl₂], [HDMA]₂[ICl₂]·Cl, [H‐4AP][IBr₂], and [HDMA]₂[IBr₂]·Br, exhibit giant birefringence values in both the visible and near‐infrared regions, while achieving an optimal balance between giant birefringence and ...
