Autor: Jan Becher, Tine J⊘rgensen, Kim Christiansen, Thomas K. Hansen
Publikováno v: Becher, J, Hansen, T K, Jørgensen, T & Stein, P 1992, ' Heterocyclic π-Donors, Macrocycles and Cage Molecules ', Bulletin des Sociétés Chimiques Belges, vol. 101, no. 7, pp. 555-568 . https://doi.org/10.1002/bscb.19921010704
Reaction of dmit‐salts 2 and bis‐alkylating agents leads to macrocycles annelated to a 1,3‐dithiole‐2‐thione ring. Intermolecular coupling of monomers MC[n,1] leads to TTF‐crowns of type A whereas intramolecular coupling of dimers MC[n,2]

Én route to molecular sensors based on TTF
Autor: Thomas K. Hansen, Paul C. Stein
Publikováno v: Hansen, T K & Stein, P C 1993, ' Én route to molecular sensors based on TTF ', Synthetic Metals, vol. 56, no. 1, pp. 1972-1977 . https://doi.org/10.1016/0379-6779(93)90357-3
We describe modifications in the tetrathiafulvalene (TTF) framework. By annelation of crownether moieties to the TTF-unit, the electronic properties of TTF could be influenced by non-covalent interactions with alkalimetal ions, which was studied by N

Autor: O. Simonson, Stephen Edge, Karikath S. Varma, Jan Becher, Adam Charlton, Poopathy Kathirgamanathan, Allan E. Underhill, Thomas K. Hansen
Publikováno v: Synthetic Metals. 53:315-324
The synthesis and electrochemical properties of several maleimide derivatives of 3-(2-aminoethyl)thiophene are described. Of the four soluble thiophene derivatives prepared only one, N -{3-(2-ethyl)thiophene}-3,4-dichloromaleimide, was capable of bei

ChemInform Abstract: The Vinylogue of Bis-4,5-methylenedithiotetrathiafulvalene: A New Electron Donor
Autor: Jan Becher, Thomas K. Hansen, Michael P. Cava, M. V. Lakshmikantham
Publikováno v: ChemInform. 23
A new electron donor vinylogue-BMDT–TTF 5 [2,2′-ethanediylidenebis(1,3,4,6-tetrathiapentalene)] has been synthesized (overall yield from 8 16%). The compound represents a structural modification of the molecular framework that has led to highly c
