Abstract
Novel (eta(6)-hexaalkoxytriphenylene)Cr(CO)(3) complexes 9 with varyin g alkyl chain lengths (C5H11 to C9H19) have been prepared with the chr omium tricarbonyl moiety being exclusively attached to one terminal ar yl ring. Differential scanning calorimetry, optical polarizing microsc opy and X-ray diffraction showed that complexes 9a-d displayed isotrop ic melting behavior. However, hexanonyloxy-substituted complex 9e disp layed a nematic N-D phase between 37 degrees and 58 degrees C. (C) 199 8 Elsevier Science S.A.
