    摘要: Polymer-based second harmonic generation materials are disclosed, including electric field poled, chromophore-functionalized polyphenylene ethers with second harmonic coefficients (d.sub.33) as high as 65.times.10.sup.-9 esu, Tg.apprxeq.173.degree. C., and with superior temporal stability of the poling-induced chromophore orientation. Procedures for simultaneously poling and diepoxide cross-linking chromophore-functionalized poly(.rho.-hydroxystyrene) are set forth, resulting in a significant improvement in the temporal stability of chromophore orientation. Chromophore immobilization is disclosed involving highly cross-linkable epoxy matrices. In a first procedure chromophore molecules are embedded in a matrix which can be simultaneously poled and thermally cured. In a second procedure, a functionalized high-.beta. chromophore is synthesized for use as an epoxy matrix component.

    摘要: The design and synthesis of a family of calix[4]arene-based nonlinear optical (NLO) chromophores are discussed. The calixarene chromophores are macrocyclic compounds consisting of four simple D-.pi.-A units bridged by methylene groups. These molecules were synthesized such that four D-.pi.-A units of the calix[4]arene were aligned along the same direction with the calixarene in a cone conformation. These nonlinear optical super-chromophores were subsequently fabricated into covalently bound self-assembled monolayers on the surfaces of fused silica and silicon. Spectroscopic second harmonic generation (SHG) measurements were carried out to determine the absolute value of the dominant element of the second-order nonlinear susceptibility, d.sub.33, and the average molecular alignment, .PSI.. A value of d.sub.33 =60 pm/V at a fundamental wavelength of 890 nm, and .PSI..about.36.degree. was found with respect to the surface normal.
