摘要：
Novel (eta(6)-hexaalkoxytriphenylene)Cr(CO)(3) complexes 9 with varying alkyl chain lengths (C5H11 to C9H19) have been prepared with the chromium tricarbonyl moiety being exclusively attached to one terminal aryl ring. Differential scanning calorimetry, optical polarizing microscopy and X-ray diffraction showed that complexes 9a-d displayed isotropic melting behavior. However, hexanonyloxy-substituted complex 9e displayed a nematic N-D phase between 37 degrees and 58 degrees C. (C) 1998 Elsevier Science S.A.
