The solvent-induced structural rearrangement of synthetic supramolecular structures typically requires a pronounced change in solvent polarity. We describe a ruthenium-based coordination cage, whose geometry and topology can be altered dramatically by usin ...

The excited-state dynamics of covalently linked electron donor−acceptor systems consisting of N,N-dimethylaniline (DMA) as electron donor and either perylene (Pe) or cyanoperylene (CNPe) as acceptor has been investigated in a large variety of solvents, inc ...
Fluorescent solvatochromic dyes and molecular rotors have attracted considerable attention as fluorogenic probes because of background-free detection of biomolecules in live cells in no-wash conditions. Herein, we introduce a push-pull boron-containing (di ...
Reaction of Ln(III) with a tetrakis(diketone) ligand H4L [1,1?-(4,4?-(2,2-bis((4-(4,4,4-trifluoro-3-oxobutanoyl) phenoxy)methyl)propane-1,3-diyl)bis(oxy)bis(4,1-phenylene))bis(4,4,4-trifluorobutane-1,3-dione)] gives new podates which, according to mass spe ...
The photophysics and excited-state dynamics of two dyads consisting of either a free-base or a zinc-tetraphenylporphyrin linked through a rigid bridge to a core-substituted naphthalenediimide (NDI) have been investigated by femtosecond-resolved spectroscop ...
Doping of organic light-emitting devices using highly luminescent molecules is a well-established strategy to improve brightness, efficiency and lifetime or to adjust emission color and color purity. Laser dyes from the pyran-containing donor-acceptor fami ...
