The mono-, di-, and triamino-substituted cyclic phenylazomethine (CPA) and diamino-substituted linear phenylazomethine (OPA) were synthesized in one-step via dehydration of aromatic amine and ketone in the presence of titanium tetrachloride. The line

Cyclization in hyperbranched polymer synthesis was first controlled on the basis of a steric effect using a Lewis acid with a bulky ligand. Only phenylazomethine oligomers having a cyclic structure were formed during the polymerization of 4,4‘-diam

[structure: see text] Highly preferential formation of novel polyphenylazomethine macrocycles was achieved by further addition of TiCl(4) and/or the monomer during the course of the polycondensation. These macrocycles have unique structures based on

Although a free rotation around a single bond gives no mechanical output, it has let us imagine a molecular motor. A para-substituted aromatic ring can be regarded as a rotator with the para-rotation axis. When it is incorporated in a wider pi-conjug

Novel linear and hyper-branched aromatic polyamides having phenylazomethine units were synthesized by the polycondensation of di- or triamine monomers containing azomethine bonds with dicarboxylic acids. The polymers obtained have a high solubility i
