Coordination chemistry of perhalogenated cyclopentadienes and alkynes. 8. Pentakis(dimethylsilyl)cymantrene [PDF]
, 1992 Starting from [q5-C5Br5]M n(CO),, the first r-complex of a cyclopentadienyl ligand with five silyl substituents, [q 5-C5(SiMe2H)5M] n(CO),, was prepared by a series of halogen-lithium exchange reactions, followed by silylation with SiMe2HCI.

Robust and Reversible Thermofluorescence in Solvent‐Free Thermoplastic Polyurethane Composites
Advanced Functional Materials, EarlyView.Thermofluorescent polymer composites with high‐contrast optical outputs are prepared by solvent‐free blending of indenoquinacridone dye into a thermoplastic polyurethane matrix. The temperature‐dependent fluorescence originates from aggregation–dissociation of the dye molecules, regulated by competing hydrogen bonds from the polymer matrix.

Using the Photostationary State of Arylazopyrazoles to Control Phase Transitions of Liquid Crystals
Advanced Functional Materials, EarlyView.A series of new arylazopyrazole photoswitches is designed as dopants for liquid crystalline materials. Unprecedented, the distribution of photoisomers at the photostationary state upon irradiation with light of specific wavelengths (365, 460, 520 nm) is used to control the liquid crystalline phase transitions under isothermal conditions, including ...
