Chiral induction by helical neighbour: spectroscopic visualization of macroscopic-interaction among self-sorted donor and acceptor π-stacks

摘要

Supramolecular induction of chirality to a it-stacked dialkoxy-naphthalene (DAN)-flber (made of achiral building blocks) from a neighbouring helical naphthalenediimide (NDI)-fiber is reported. CD-studies helped in understanding the nature of co-assembly in the donor-acceptor chromophore mixture from molecular to macroscopic scale. Helical assembly plays a key role in many elegant functions performed by biopolymers in living systems with ultimate perfection.
