Synthesis of Cyclotriphosphazenes Containing Cyanostilbenes with Different Terminal Substituents
摘要:
The synthesis and mesomorphic properties of a class of cyclotriphosphazenes containing cyanostilbene groups with different terminal substituents (-H, -CH3, -OCH3, -CN) are described. All the resulting compounds are characterized by H-1, C-13, and P-31 NMR, matrix-assisted laser desorption/ionization time of flight, and elemental analysis. The thermal behaviors of cyclotriphosphazene derivatives are studied by the means of differential scanning calorimetry and polarizing optical microscopy. Nematic phases are observed in cyclotriphosphazenes with terminal substituents (-CH3, -OCH3, CN).

The invention relates to conducting and semi-conducting photoreactive compounds, represented by the general formula (I), to the use of these compounds for the preparation of oriented and/or orientation layers; and to their use in the construction of unstructured and structured optical, electro optical or optoelectronic elements and multi-layer systems.
Novel polycyanate and polycyanamide compositions containing one or more mesogenic or rodlike moieties, when cured, result in products having improved properties.
