側鎖にアルコキシビフェニルをもつシクロトリホスファゼン液晶の構造

抄録

X-ray measurements of hexakis(4-(4'-alkyloxy)biphenoxy)cyclotriphosphazenes [PN(OC₆H₄C₆H₄OC_nH_2n+1)₂] 3(HACP, n=7-9) confirm the previous mesophase identification. The apparent molecular length measured in the mesophase compares to twice the length of an alkyloxybiphenyl side groups. Specific features are added to the usual features of the nematic and smectic diffraction patterns which show the molecular arrays in directions parazllel and perpendicular to the director both reflect the peculiar shape of their cyclotriphosphazenes.
