Benzodichalcogenophenes with perfluoroarene termini.
نویسندگان
چکیده
Benzodichalcogenophenes are functionalized at their termini via SN Ar reactions of their bismetalates with perfluoroarenes. The identities of X, Y, and W are varied to study the effects on LUMO energy levels and crystallization motif. X-ray crystallography reveals that nearly all new derivatives crystallize with coplanar ring systems within slipped 1D or 2D pi-stacks.

متن کاملBinary stacks of [CuC6F5]4 with arenes.
Formation of the first binary stacks of an intact organocopper aggregate with the arenes naphthalene and 2,2'-bithiophene is reported; crystallographic data suggest that the supramolecular assembly process is supported by Cu-pi, Cu-S, and perfluoroarene-arene pi-interactions.

Density-functional theory (DFT) is employed to investigate the structural, electronic, and transport properties of several isomeric fluoroarene-oligothiophene-based semiconductors. Three oligothiophene systems varying in the perfluoroarene group positions within the molecule are studied to understand the electronic structure leading to the observed mobility values and to the n- or p-type behavi...

متن کاملArene-perfluoroarene interactions in crystal engineering. XV. Ferrocene-decafluorobiphenyl (1/1).
The title crystal, [Fe(C5H5)2].C12F10, comprises infinite chains of alternating component molecules, linked through face-to-face contacts of nearly parallel cyclopentadienyl and pentafluorophenyl rings. The decafluorobiphenyl molecule has a crystallographic twofold axis and the Fe atom of the ferrocene molecule is on a crystallographic inversion centre, with both cyclopentadienyl rings disordered.
