Abstract
Di-1-naphthyl ditelluride (Te(2)naphthyl(2)) is characterized by two low-energy excited states. The corresponding electronic transitions nTe -> sigma(*) Te-Te and nTe -> pi(*) naphthyl CT give rise to absorptions at lambda(max) = 403 and 311 nm, respectively. In solution nTe -> sigma(*) excitation leads to the cleavage of the Te-Te bond. In contrast to Te(2)naphthyl(2) in the dissolved state the ...
Abstract
Di-1-naphthyl ditelluride (Te(2)naphthyl(2)) is characterized by two low-energy excited states. The corresponding electronic transitions nTe -> sigma(*) Te-Te and nTe -> pi(*) naphthyl CT give rise to absorptions at lambda(max) = 403 and 311 nm, respectively. In solution nTe -> sigma(*) excitation leads to the cleavage of the Te-Te bond. In contrast to Te(2)naphthyl(2) in the dissolved state the solid compound shows a luminescence (lambda(max) = 576 nm) which originates from nTe -> pi(*) naphthyl CT triplet. (c) 2008 Elsevier B.V.
