Oblique packing and tunable excitonic coupling in DNA-templated squaraine rotaxane dimer aggregates

This publication describes how to consistently obtain an elusive oblique packing arrangement by using DNA to bring squaraine rotaxanes into close proximity. Further fine tuning of excitonic interactions is possible via synthetic modification of squaraine rotaxanes.
