Density functional theory study of the optical and electronic properties of oligomers based on phenyl-ethynyl units linked to triazole, thiadiazole, and oxadiazole rings to be used in molecular electronics

The Journal of Chemical Physics, 2010
In the present work, we have studied from a theoretical perspective the geometry and electronic properties of the series of related compounds 2,5-bis(phenylethynyl)-1,3,4-thiadiazole, 2,5-bis(phenylethynyl)-1,3,4-oxadiazole, and 2,5-bis(phenylethynyl)-1,2,4-triazole as candidates for electron-conducting polymers and compounds with desirable (opto ...

Stiefel–Whitney Classes, United K-theory and Real Embeddings of Number Rings

K-Theory, 2005
The author studies the relations among the various Stiefel-Whitney classes associated to the real embeddings of a number ring \(A\), using a computation of the united \(K\)-theory of the algebraic \(K\)-theory spectrum \(KA\) of \(A\). More precisely, let \(F\) be a number field, let \(S\subset {\mathcal O}_F\) be a set of primes in its ring of ...
