(η6-hexaalkoxytriphenylene)Cr(CO)3 complexes 9 with varying alkyl chain lengths (C5H11 to C9H19) have been prepared with the chromiumtricarbonyl 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
