Abstract: The EFISH response of a push–pull phthalocyanine (Pc), compound <B>2</B>, bearing SO2C8H17 (acceptor) and OC8H17 (donor) substituents has been measured at <F>λ=1.9</F> μm. The result has been compared to that of compound <B>1</B>, including a triazolehemiporphyrazine (Thp) subunit within the bridging path to the donor moiety. After correcting for the (symmetric) electronic contribution to γEFISH, the data show that the Thp subunit induces a reduction and a change of the sign in βEFISH. [Copyright &y& Elsevier]
