    • High reactivity of acceptor 1 toward self-condensation makes the separation of acceptor 1 impractical for styryl TCP chromophores.

    • The spectroscopic parametrizations along with the Mataga-Nishimoto electron-repulsion potential were used, as implemented in the ZINDO code. The INDO calculations were coupled to a single-configuration interaction (SCI) scheme, previously proven successful at predicting reliable β values. The 30 highest occupied and 30 lowest unoccupied molecular orbitals were active in the SCI procedure, (a) Dewar, M. J. S.; Zoebisch, E. G.; Healy, E. F.; Stewart, J. J. P. J. Am. Chem. Soc. 1985, 107, 3902.

    • note
    • -30 was used for conversion. Comparison of β for all chromophores at a single excitation wavelength, say 1.9 μm, is not useful because of various resonance effects, resulting from the wide range of spectral windows between chromophores.

    • We thank a reviewer for clarifying that the intermolecular electronic interactions and the poling field on individual molecules cannot be treated independently when we generate an acentric order by applying an external poling field.

    • note
    • As a reviewer suggested, luminescence is a common issue with HRS measurements, But interference from the luminescence of TCP chromophores is not a complication in these measurements. Because we use a spectrograph to disperse the radiation coming from the sample, we can discern the multiphoton-excited fluorescence background from the HRS signal through analysis of the line width. In these experiments, the HRS intensity was sufficiently intense relative to the luminescence background that it could be readily identified and measured.
