Abstract

The efficient photo-triggered surface relief formation in the H-boned supramolecular liquid crystalline system was performed for the first time. This supramolecular framework leads to facile and successful detachment of azobenzene unit from the SRG inscribed film with exact retention of the morphological periodicity.
