Cycloaddition vs. conjugative Michael-type addition of 2-ethoxy-3-morpholinobuta-1,3-diene with nitroolefins

The reactivity of the title dienamine towards conjugated nitroolefins has been investigated. With 1-nitrocyclopentene carbocyclic products largely predominated, whereas with 1-nitrocyclohexene only Michael-type products were formed. The behaviour of β-nitrostyrene was found to be dependent on the reaction conditions used.

Role of alkyl substituents in the structure and luminescence properties of discrete terbium(III)-lithium(I) Β-Diketonates

Functionalized perfluoroalkyl lithium β-diketonates LiL react with terbium (III) salts in methanol to give heterobimetallic complexes of general formula [(TbL3)(LiL)(MeOH)]. The length of both fluoroalkyl and hydrocarbon substituents in ligand was found to affect the crystal packing of metal complexes. Photoluminescence of heterobimetallic β-diketonates in the solid state is reported.

Mechanistic Insights into the Triplet Sensitized Photochromism of Diarylethenes

Operating photoswitchable molecules repetitively and reliably is crucial for most of their applications, in particular in (opto)electronic devices, and related to reversibility and fatigue resistance, which both critically depend on the photoisomerization mechanism defined by the substitution pattern. Two diarylethene photoswitches bearing biacetyl triplet sensitizers either at the periphery or at the core were investigated using both stationary as well as transient UV/Vis absorption spectroscopy ranging from the femtosecond to the microsecond time scale. The diarylethene with two biacetyl moieties at the periphery is switching predominantly from the triplet excited state, giving rise to an enhanced fatigue resistance. In contrast, the diarylethene bearing one diketone at the photoreactive inner carbon atom cyclizes from the singlet excited state and shows significantly higher quantum yields for both cyclization and cycloreversion.

Switching diarylethenes reliably in both directions with visible light

A diarylethene photoswitch was covalently connected to two small triplet sensitizer moieties in a conjugated and nonconjugated fashion and the photochromic performance of the resulting compounds was investigated. In comparison with the parent diarylethene (without sensitizers) and one featuring saturated linkages, the conjugated photoswitch offers superior fatigue resistance upon visible-light excitation due to effective triplet energy transfer from the biacetyl termini to the diarylethene core. Our design makes it possible to switch diarylethenes with visible light in both directions in a highly efficient and robust fashion based on extending π-conjugation and by-product-free ring-closure via the triplet manifold. Flipping the spin: When biacetyl triplet sensitizers were linked to a dithienylethene core in a conjugated fashion, the photoswitching performance dramatically improved. This design makes it possible to switch diarylethenes with visible light in both directions in a highly efficient and robust fashion.
