Interstrand communication between 2′-N-pyren-1-ylmethyl-2′-amino-LNA monomers in nucleic acid duplexes: directional control and signalling of full complementarityElectronic supplementary information (ESI) available: details of thermal denaturation, fluorescence and molecular modelling experiments. Lowest energy structure of ON8ON11. Steady-state fluorescence emission spectra as Fig. 4; positions 11 and 12. See http://www.rsc.org/suppdata/cc/b4/b404446k/

Very efficient interstrand communication systems in nucleic acid duplexes, based on pyrene excimer formation between 2′-N-pyren-1-ylmethyl-2′-amino-LNA monomers, demonstrate the versatility of functionalized 2′-amino-LNA monomers for Ångström-scale chemical engineering.
