New platforms integrating ethynyl-grafted modules for organogels and mesomorphic superstructures.
A methyldiacylaminophenyl core substituted with gallic derivatives and alkynyl functions has been synthesized from 2,6-diamino-4-iodotoluene. By heating the iodo and ethynyl molecules, typical columnar mesophases are observed and the C(12) synthons bearing a protected terminal alkyne group gelified acetone, via the formation of interlocked fibers which are promoted by intermolecular hydrogen bonding.
