The structure of 6,6′-biquinolyl and its dication in solution

摘要

Conformational analysis of 6,6′-biquinolyl and its dication was performed using dipole moments and data from electric and magnetic birefringence. The rotation angles between the quinoline rings for thecis- andtrans-conformers in solution are ∼50°. The emergence of positive charges on both heteroaromatic rings does not result in noticeable changes in the spatial struc
