:Sequence-defined polymer

{{context|date=February 2018}}

Sequence-defined polymer (Syn. sequence-specific polymer, sequence-ordered polymer) is a uniform macromolecule with an exact chain-length and a perfectly defined sequence of monomers.{{Cite journal|last1=Lutz|first1=Jean-François|last2=Ouchi|first2=Makoto|last3=Liu|first3=David R.|last4=Sawamoto|first4=Mitsuo|date=2013-08-09|title=Sequence-Controlled Polymers|journal=Science|language=en|volume=341|issue=6146|pages=1238149|doi=10.1126/science.1238149|issn=0036-8075|pmid=23929982|s2cid=206549042}}{{Cite journal|last=Lutz|first=Jean-François|date=2017-12-01|title=Defining the Field of Sequence-Controlled Polymers|journal=Macromolecular Rapid Communications|language=en|volume=38|issue=24|pages=n/a|doi=10.1002/marc.201700582|pmid=29160615|issn=1521-3927}} In other words, each monomer unit is at a defined position in the chain e.g. peptides, proteins, oligonucleotides.{{Cite journal|last1=Lehto|first1=Taavi|last2=Wagner|first2=Ernst|date=2014-12-23|title=Sequence-defined polymers for the delivery of oligonucleotides|journal=Nanomedicine|language=EN|volume=9|issue=18|pages=2843–2859|doi=10.2217/nnm.14.166|pmid=25535686}} Sequence-defined polymers constitute therefore a subclass of the field of sequence-controlled polymers.{{cite journal |last1= Aksakal|first1= R.|last2= Mertens|first2= C.|last3= Soete|first3= M.|last4= Badi|first4= N.|last5= Du Prez|first5= F. |title= Applications of Discrete Synthetic Macromolecules in Life and Materials Science: Recent and Future Trends |journal= Advanced Science |year= 2021|volume=2021 |issue= 2004038|pages= 1–22 |doi= 10.1002/advs.202004038|pmid= 33747749|pmc= 7967060|doi-access= free}}
