Wide-Range 2D Lattice Correlation Unveiled for Columnarly Assembled Triphenylene Hexacarboxylic Esters

Dipole bridge: Liquid‐crystalline (LC) triphenylenes (see picture) self‐assemble columnarly into a hexagonal geometry with a wide‐range 2D lattice correlation, for which distal and proximal dipole–dipole interactions are considered responsible. By virtue of the strong intercolumnar interaction, the...

Zusammenfassung:Dipole bridge: Liquid‐crystalline (LC) triphenylenes (see picture) self‐assemble columnarly into a hexagonal geometry with a wide‐range 2D lattice correlation, for which distal and proximal dipole–dipole interactions are considered responsible. By virtue of the strong intercolumnar interaction, the LC columns of the triphenylene can spontaneously align homeotropically on the 12 different substrates examined (POM=polarized optical microscopy).
