Benzodichalcogenophenes with Perfluoroarene Termini
摘要:
Benzodichalcogenophenes are functionalized at their termini via SNAr 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.
