a, SEC charts of the crude product of reactions with various I′/M ratios. b, c, M n and M w 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.
