摘要:
Conjugated mono-, oligo- and polymers of benzo[b]thiophene and bisbenzo[b]thiophene are useful as semiconductors or charge transport materials in optical, electrooptical or electronic devices including field effect transistors, electroluminescent, photovoltaic and sensor devices.
摘要:
Described herein are compounds of formula I wherein M1, M2 and M3 have the meanings recited in the disclosure, liquid crystalline mixtures and polymers containing them, and the use of the compounds of formula I, the liquid crystalline mixtures and the polymers containing them in optical and electrooptical devices like liquid crystal displays or projection systems, patterned films and optical elements like polarizers, retardation films, compensators, color filters, holographic elements or polarization beam splitters, for photoswitching, in anisotropic membranes for the permeation of gases or fluids, adhesives, synthetic resins with anisotropic mechanical properties, cosmetic or pharmaceutical compositions, UV absorbers and sunscreens, diagnostics or liquid crystal pigments, for decorative and security applications, in nonlinear optics, optical information storage or as dopants.
