To build the Q I structure, we first place the monomer heads along the minimal surface of the gyroid and then shift the entire monomer 0.3 nm outwards along the normal to the surface to create a channel. Shifting over 0.3 nm tends to destabilize the system due to excessive overlaps between tail groups. The number of monomers we place in a unit cell is determined by the experimental weight composition of the monomer and glycerol (79% monomer, 20% glycerol, and 1% photo-initiator ) for the stable Q I phase. The LLC structure so formed has several overlaps between atoms and thus needs to be energy minimized.
