    Abstract

    Surface SHG was observed, when a quartz plate with a submonolayer of viologen molecules on the surface was dipped into the heptane solution of 4,4′-dialkoxyazobenzene. Isomerization of the azobenzene moiety from the trans- to cis-form induced large increase in the SHG. The SHG was ascribed to intramolecular charge-transfer from the alkoxy- to the azo group of the non-centrosymmetrically aligned isomers on the quartz plate.
