Tailored Solution‐Based N ‐heterotriangulene Thin Films: Unravelling the Self‐Assembly

The ability of a series of bridged triarylamines, so‐called N ‐heterotriangulenes, to form multilayer‐type 2D‐extended films via a solution‐based processing method was examined using complementary microscopic techniques. We found that the long‐range order, crystallinity, and layer thickness decisively depend on the nature of the substituents attached to the polycyclic backbone. Owing to their flat core unit, compounds exhibiting a carbonyl unit...
