摘要:
                                AbstractThe thermal behavior of the metallomesogens [Ln(C12C16dbm)3(phen)] (Ln = La, Nd, Eu, Gd, Tb, Dy, Er, Yb; C12C16dbm = 1‐(4‐dodecyloxyphenyl)‐3‐(4‐hexadecyloxyphenyl)propane‐1,3‐dionate; phen = 1,10‐phenanthroline) was investigated. The complexes of the light lanthanides (Ln = La, Nd) are not mesomorphic, whereas the complexes of the heavy lanthanides (Ln = Eu, Gd, Tb, Dy, Er, Yb) exhibit a monotropic smectic A phase (SmA). A model for themolecular organization of the molecules in the smectic A phase is proposed. The luminescence properties of the complexes [Eu(C12C16dbm)3(phen)], [Er(C12C16dbm)3(phen)], and [Yb(C12C16dbm)3(phen)] were investigated. (© Wiley‐VCH Verlag GmbH & Co.
