NLO Responses of Anils in Solution Structure-Property Relationships 

The last columns gather the / (K)/ (E) contrasts related to both the EFISHG and HRS responses, a) There is no result for compounds 6 and 9 in the K forms since they are not stable. 

Combining these donor acceptor effects on the same system leads to a smaller ratio (and higher contrast) for compound 3 than for compound 5. For compound 3, the donor effect of the NH2 group is enhanced by the presence of the Br atom whereas for compound 5, it is balanced by the NO2 group. Indeed, adding a Br in R to get compound 3 reduces hrs(I ) enhances hus(E).
