Abstract
At level best: A strategic synthesis of a new class of poly(p-phenylene vinylene)-bearing annulated alkene units from a parent poly(p-phenylene ethynylene) is described (see scheme). The gold-mediated cycloisomerization reaction of alkynes with appended hydroxy-group reacting partners delivers products having a stark increase in chain rigidity and planarity, as evidenced by pronounced photophysical changes. Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such documents are peer-reviewed, but not copy-edited or typeset.
