N2 - The first synthesis of a novel ligand, 1-hydroxy-2,3,5,6,7-pentahexyloxy-9, 10-anthraquinone, is reported. Analogous to the well-known β-diketone system. 1-hydroxy-2,3,5,6.7-pentaalkoxy-9,10-anthraquinones also form metal complexes. The first copper complex of discotic liquid crystalline 1-hydroxy-2,3,5,6,7-pentahexyloxy-9,10-anthraquinone has been prepared. The metal complex shows a columnar mesophase upon doping with trinitrofluorenone, an electron acceptor molecule. The mesomorphic behavior was studied by polarizing microscopy and differential scanning calorimetry.
