This contribution reports a new approach to the synthesis of thin-film second-order nonlinear optical (NLO) materials in which self-assembled chromophore-containing multilayer structures are built up in the repeating reaction sequence: I3Si(CH2)2C6H4CH2I (Cp), 4-[N,N-bis(3-hydroxypropyl)amino]styryl-4'-pyridine (Ch), Cl3SiOSiCl2OSiCl3 (Si), polyvinylalcohol (PVA). The resulting multilayer structures have been characterized by optical and XPS spectroscopy, advancing contact angle measurements, null ellipsometry, and NLO properties. The latter measurements reveal multilayer superlattices with good structural uniformity and that MZzz = 2 x 10-7 esu at λ = 1064 run (Mzzz = 6 x 10-7 esu for a single CpCh monolayer of 22 A estimated thickness).
