Phosphorescence within benzotellurophenes and color tunable tellurophenes under ambient conditions.
نویسندگان
چکیده
The zirconium-mediated syntheses of pinacolboronate (BPin) appended benzo[b]tellurophenes and two phenyl/BPin substituted tellurophene isomers with different colors of emission have been achieved. These species are new additions to an emerging class of inorganic heterocycles that display visible phosphorescence in the solid state under ambient conditions.

Long-afterglow metal–organic frameworks: reversible guest-induced phosphorescence tunability
Luminescent metal–organic frameworks (MOFs) have received much attention due to their wide structural tunability and potential application in light-emitting diodes, biological imaging and chemical sensors. However, successful examples of long-persistent afterglow MOFs are still quite limited to date. In this work, we report that two types of Zn-terephthalate (TPA) MOFs (namely [Zn(TPA)(DMF)] (1...
متن کاملPhosphorescence of gadolinium(III) chelates under ambient conditions
The gadolinium(III) chelates Gd(dtpaH2), Gd(hfac)3, Gd(tta)3 and Gd(qu)3 with dtpa1⁄4 1,1,4,7,7-diethylenetriaminepentaacetate, hfac1⁄4 hexafluoroacetylacetonate, tta1⁄4 thenoyltrifluoroacetonate and qu1⁄4 8-quinolinolate (or oxinate) show a phosphorescence under ambient conditions. While the UV emission of Gd(dtpaH2) at kmax 1⁄4 312 nm comes from a metal-centered ff state, the bluish (kmax 1⁄4...
متن کاملPhosphorescence doping in a flexible ultramicroporous framework for high and tunable oxygen sensing efficiency.
Doping very small amounts of Ru(II) into a flexible, ultramicroporous, fluorescent Zn(II) coordination polymer produced phosphorescent materials with very high and tunable oxygen quenching efficiency; and a simple color-changing ratiometric oxygen sensor has been constructed.
متن کاملStabilizing triplet excited states for ultralong organic phosphorescence.
The control of the emission properties of synthetic organic molecules through molecular design has led to the development of high-performance optoelectronic devices with tunable emission colours, high quantum efficiencies and efficient energy/charge transfer processes. However, the task of generating excited states with long lifetimes has been met with limited success, owing to the ultrafast de...
متن کاملSynthesis and Luminescence of RhIII ( phpy ) 2 ( S ∪ E ) Complexes
Complexes of the general composition Rh(phpy)2(S∪E) with phpy− = 2-(2-pyridyl)phenyl and S∪E− = diethyldithiocarbamate, 2-pyridinethiolate and 2-quinolinethiolate were prepared and characterized. The complexes with S∪E− = diethyldithiocarbamate and 2-pyridinethiolate show a low-temperature luminescence which originates from a phpy ππ∗ intraligand triplet. For the complex with S∪E− = 2-quinoline...
