Negative mode MS/MS to read digital information encoded in sequence-defined oligo(urethane)s: A mechanistic study

[Display omitted] •Small polyurethanes (PUs) were studied to anticipate MS/MS behavior of long chains.•Three mechanisms were evidenced for O(CO)NH bond cleavage in deprotonated PUs.•Main issue with long chains was not related to CID but to negative mode ESI yield.•A new design of PU end-groups allow...
