## Abstract A new pentafunctional monomer (3a) was prepared by acylation of silylated 3,5‐diaminobenzoic acid (DABA) with 3,5‐bisacetoxybenzoyl chloride. The polycondensation of this monomer or its trimethylsilyl ester yielded a hyperbranched poly(ester‐amide) having a nearly alternating sequence o

Abstract
It is shown that the anhydride, the amide, and the esters of 3,5‐dinitrobenzoic acid all give highly coloured π‐complexes with a variety of polycyclic aromatic and heterocyclic compounds. The complexes derived from the anhydride contain one molecule of the anhydride to two molecules of the electron‐donor, whilst the others are of the 1 : 1 type.
