Fig. 4. PL spectroscopy in toluene.

Fig. 4

(A) PL spectra of Homo-1 (magenta) and Homo-3 (green) excited at 550 and 490 nm, respectively. (B to H) Co-1-k (k = 1 to 7) excited at 550 nm (circles) and 490 nm (solid lines). (I) UV/vis spectra of Homo-1 + Homo-3 (solid line) and Co-1-4 (dotted line) with normalization at 490 nm. (J) PL spectra of Homo-1 + Homo-3 (solid line) and Co-1-4 (dotted line) upon excitation with 490-nm light. (K) Illustration of exciton transfer behavior: interwire exciton transfer in Homo-1 + Homo-3 is negligible, whereas intrawire exciton transfer in Co-1-4 is efficient.
