Extended Data Fig. 8 | Analytical SEC, UV-vis absorption, emission,
IR and Raman spectroscopy data for armchair-type GNR 8. a, S EC
charts of armchair-type GNR 8 obtained by the Scholl reaction of fjord-
type GNR 2 with different polymer lengths. b, UV-vis absorption spectra
of 8. c, Emission spectra of 8. d, Observed IR spectra of GNR 8 with
different polymer lengths (red, yellow, blue and purple lines) and IR
spectrum of dimer 11 (black line) predicted by DFT calculations at the
B3LYP/6-31G(d) level of theory. e, Raman spectra of GNR 8 with
different polymer lengths (red, yellow, blue and purple lines), obtained
by excitation by a 532-nm laser.
