Extended Data Fig. 5 | Analytical SEC, IR and Raman spectroscopy data
for fjord-type GNR 7. a, SEC charts of the crude product of reactions with
various I′/M ratios. b, c, Mn and Mw profiles versus M/I′ and conversion of
the monomer in the living APEX polymerization. d, Observed IR spectra
of GNR 7 with different polymer lengths (blue, green, yellow and red 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 7 with
different polymer lengths (blue, green, yellow and red lines), obtained with
excitation by a 532 nm laser.
