摘要 <p>PCT No. PCT/GB94/01760 Sec. 371 Date Jan. 29, 1996 Sec. 102(e) Date Jan. 29, 1996 PCT Filed Aug. 11, 1994 PCT Pub. No. WO95/04953 PCT Pub. Date Feb. 16, 1995Optically non-linear materials suitable upon repeated Langmuir-Blodgett dipping for forming Z-type (head-to-tail) films for second harmonic generation include hemicyanine dyes which are very unsymmetrical, i.e. which have hydrophobic substituents differing in size by at least 4 carbon atoms, each end of a hydrophilic chromophore. A suitable dye is E-N-octadecyl-4-[2-(4-dibutylaminophenyl)ethenyl]quinolinium iodide.</p>
