From: High conductance values in π-folded molecular junctions
(a) Solid-state structure of trimer-NHBoc with two DMSO molecules (highlighted in yellow). (b) Chemical structure of A-NHBoc. (c) NMR spectra of the foldamer NHBoc series at 25 °C. (d) Two-dimensional DOSY NMR of pentamer-NHBoc at 25 °C. (e) VT-NMR of pentamer-NHBoc. (f) Absorption and (g) PL spectra of the NHBoc foldamer series at 25 °C. Infrared ion dip spectrum of (h) dimer-NHBoc and (i) trimer-NHBoc. The triangles in b–e indicate the signals that correspond to anthracene protons.
