“…Uniform oligoesters are useful model compounds to study and understand, for example, the crystallization behavior of the corresponding high-molecular-weight polymers. The first pioneering reports describing the synthesis of uniform oligoesters date back more than 20-30 years and were published by Zahn 5 and Wegner. 42 Zahn et al prepared uniform ethylene terephthalate oligomers containing up to ten repeat units via a synthetic strategy that combined simple repetitive synthesis of elementary building blocks with fragment condensation to prepare the final oligomers of the desired length.…”

“…However, an increasing number of synthetic methods has become available that allows access to uniform and sequence-specific non-natural oligomers. In the broadest sense, uniform non-natural oligomers are of interest (i) as model compounds that can help to establish structure-property relationships for the corresponding high-molecular-weight polymers, [4][5][6][7] and (ii) as foldamers. [8][9][10] As model compounds, uniform, nonnatural oligomers can facilitate the analysis of comonomer distribution and stereochemistry of high-molecularweight copolymers and allow to study the influence of these parameters on e.g.…”

Oligomers with well-defined chain lengths are of interest as foldamers, are important as model compounds for high-molecular-weight polymers and find application in electrooptic and sensory devices. This account presents an overview of the strategies that are available for the synthesis of eight important classes of uniform oligomers. The continuous refinement of the synthetic methods allows the preparation of ever longer oligomers in higher yields and also makes it possible to introduce special functional groups. These improvements could lead to materials with new or improved properties and underline the importance of synthetic organic chemistry for the development of new functional materials.

“…Pioneering synthetic work in this field was carried out by Zahn et al (Pénisson & Zahn, 1970;Zahn & Gleitsman, 1963), followed by Haslin et al (Haslin et al, 1980) and more recently by Brooke et al (Brooke et al, 2002). Possible PET oligomers can have free carboxylic group and hydroxyl group or both of them on the ends of the chain (Fig.…”
