AI Article Synopsis

  • The research highlights the use of functional oligomers made from π-conjugated oligofluorenes to create amorphous monolayers that can selectively assemble.
  • These monolayers show strong lateral charge transport abilities in self-assembled monolayer field-effect transistors, even across long distances and amid mixed types of molecules.
  • The findings suggest that this oligomer approach could inspire innovative designs for new self-assembling semiconducting materials.

Article Abstract

The use of functional oligomers of π-conjugated oligofluorenes led to a region-selective assembly of amorphous monolayers which exhibit robust lateral charge transport pathways in self-assembled monolayer field-effect transistors over long distances and even in mixed monolayers of semiconducting and insulating molecules. This oligomer concept might stimulate a new molecular design of self-assembling semiconducting materials.
