26. Reduction potential of 4-methoxyarylmaleimide (5, see Supporting data) was measured with the differential pulse voltammetry to be -1.03 V in DMF (potential are reported by reference to SCE), no reduction wave was not detected for the D-A adduct of 5 with furan (compound 6, see Supplementary data) under identical conditions

28. Compound 4 was prepared according to the literatures: J.O. Park, and S.H. Jang J. Polym. Sci., Part A: Polym. Chem. 30 1992 723
29. 1H NMR spectrum, the endo and exo isomers of 4 exist in 1:1 ratio, and the sample was not separated and used for reaction
30. Characterization data of endo and exo 2 are provided in Supporting data

32. Characterization data of dyad 1 are provided in Supporting data
33. The quantum yields presented in this letter were calculated by reference to 9,10-diphenylanthracene; the excitation wavelength is 370 nm
34. For each fluorescence measurement, a 2 ml solution of endo 2 in DMF was prepared and carefully sealed. The solution was kept in a constant temperature trough for 10 min (the temperature was controlled with a thermocouple). After that, the fluorescence spectrum of endo 2 was measured using a Hitachi-4500 spectrometer in a quartz cell. The fluorescence spectra of exo 2 were measured similarly
