Towards the IR limit of the triplet-triplet annihilation-supported up-comersion: Tetraanthraporphyrin

A study was conducted to demonstrate the infrared (IR) limit of the triplet-triplet annihilation (TTA)-supported up-conversion (UC) of tetraanthraporphyrin. The fundamental advantage of the TTA-supported UC is its independence on the coherence of the excitation light. It was demonstrated that the TTA-supported UC approach also resolves another demanding limitation of the conventional methods for UC. Another significant advantage of the new approach, was the low intensity needed to achieve high quantum yields on the order of 2-4% in inorganic solutions. The combination of these characteristics and possibilities make energetically conjoined TTA-UC suitable for diverse applications, such as all-organic, flexible, transparent displays, and up-converter devices.

A general synthetic method for 2-substituted anthracenes

Anthracenes bearing a primary alkyl, ω-hydroxyalkyl, aryl or vinyl substituent at the 2-position are conveniently prepared by a copper-catalyzed Grignard reaction on 2,3-epoxy-1,2,3,4-tetrahydroanthracene, followed by dehydration - dehydrogenation of the resulting alcohols with tetrachloro-1,2-benzoquinone (o-chloranil).

Chemistry of Bridged Aromatics. A Study of the Substituent Effect on the Course of Bond Cleavage of 9,10-Dihydro-9,10-ethanoanthracenes and an Oxyanion-Assisted Retro-Diels-Alder Reaction

The retro-Diels-Alder reactions of 9,10-dihydro- and 1,4,9,10-tetrahydro-9,10-ethanoanthracenes are dramatically accelerated by an oxyanion substitution on the 2? component, i.e., the ethano bridge.Studies of related systems bearing anionic, cationic, and radical substituents indicate that the cycloreversion is concerted and occurs only if both 4? and 2? fragments are highly resonance stabilized.

Synthesis and Properties of 1,1-Dihalogenocyclopropanthracenes

The synthesis of 1,1-difluoro-1H-cyclopropanthracene (3) is described.The key step of the synthesis is the cycloaddition of 1,2-dichloro-3,3-difluorocyclopropene (6) to 2,3-dimethylidene-1,2,3,4-tetrahydronaphthalene (5).The 13C-NMR. spectrum of 3 is assigned on the grounds of C,F-coupling constants, selective H-decoupling and the resulting residual C,H-coupling.The 1,1-dichloro derivative 4 was synthesized by the same route, but could not be isolated pure.Experiments for the reduction to 1H-cyclopropanthracene (2) and for the ionization of 3 or 4 to the cation 16 failed.
