  Chalcogens as electron donors for selected nonlinear optic phores

  摘要：

  Three different heteroaromatic charge transfer chromophores, e.g. donor(D)acceptor(A)-substituted thieno[3,2-b]thiophenes 3 and 4, D-substituted thieno [2,3-c] pyridinium salts 7 and 2-(2'-thienyl)pyridinium salts 10 have been prepared, Alkylchalcogenic ethers were used as D-groups. The molecular first hyperpolarizabilities beta were determined by the EFISH method in the case of 3 and 4 and by the HRS method in the case of the ionic compounds 7 and 10, Substitution of the ether oxygen atom by sulfur increases markedly the beta value which is not further increased by the higher chalcogens selenium and tellurium.

  Compounds of the formula I ##STR1## in which R is a C.sub.1 - to C.sub.22 -alkyl radical, A.sup.1 and A.sup.2 are hydrogen or methyl or, A.sup.1 is hydrogen and A.sup.2 is the nitro group, and B is the cyano group, the nitro group or an electron-attracting organic group having a double bond which is in conjugation with the thieno\x9b3,2-b!thiophene ring system, have a high dipole moment and a high polarizability and are suitable for purposes of nonlinear optics. If R in the formula I is a C.sub.12 - to C.sub.22 -alkyl radical, monomolecular layers can be applied to a substrate by the Langmuir-Blodgett method. The resulting layer elements are suitable, inter alia, as waveguides.

  式I的化合物##STR1##中，R为C.sub.1-C.sub.22烷基基团，A.sup.1和A.sup.2为氢或甲基，或者A.sup.1为氢，A.sup.2为硝基基团，B为氰基，硝基基团或具有与噻吩\x9b3,2-b!噻吩环系共轭的电子吸引有机基团，具有高偶极矩和高极化度，适用于非线性光学目的。如果式I中的R为C.sub.12-C.sub.22烷基基团，则可以通过Langmuir-Blodgett法将单分子层应用于底物。由此产生的层元素适用于波导等用途。
