Rational design of mols. that exhibit a thermotropic bicontinuous cubic (Cub) phase has been earnestly desired. In this work, we describe the suitable selection of a mol. motif that has enabled the systematic exploitation of eight new series of Cub-phase mols. with sym. mol. cores, N-n (1), PB-n (2), S-n (3), and PEB-n (4), and unsym. cores, B-N-n (5), B-PB-n (6), B-S-n (7), and B-PEB-n (8). These eight series all originate from achiral chain-core-chain type rod-like mols. that exhibit two types of Cub phases, an achiral Ia3d phase, and a chiral phase. All the Ia3d phases formed were found to be isomorphous structures, with their cell dimensions being proportional to the core size, and the same was true for the latter chiral phase. We demonstrated that the formation is mainly governed by the segregation between core and alkyl moieties of the mols., and thus, by the weight fraction of the core portion fcore. This work also demonstrates that the central dicarbonylhydrazine linkage bearing intermol. hydrogen bonding ability exhibits a pinning effect that prevents slippage of π-stacks of mols., which is critical for the formation of the two Cub phases that are composed of chiral networks with twisted mol. arrangements. In each series, the emergence of spontaneous chirality formation that occurred in the chiral phase was limited to between 0.36 and 0.50 in the range of fcore. An interesting insight was that the introduced unsymmetry of the mol. core strongly influenced the phase behavior, which lowered the temperature range of Cub phases to around that of the smallest core series B-n, while the high temperature limit (Tc) was roughly proportional to the core size, as determined by the strength of intermol. π-π interactions.
