The minimalistic BTA model employed herein is the implicit-solvent version of the molecular model developed recently in Ref. 48. The topology of the monomer is identical, while the bonded and non-bonded interaction parameters have been adapted to work consistently in the absence of explicit-solvent molecules . This model is representative of 3-fold symmetric monomers (having three solvophilic arms that surround a core) which interact directionally with each other in a good solvent (including, but not limited to, e.g., BTA monomers with alkyl side chains immersed in organic solvents, etc.). Initially built starting from the topology of fine-grained MARTINI-based CG BTA-C6 monomers, the BTA model has a more abstract and general structure, optimized to obtain a behavior consistent with that of higher-resolution models. The BTA monomer is composed by 18 beads of three different types (see Figure ). At the center of the molecule there is a CG-bead (Figure : in red), containing a rigid central dipole composed of two small, charged beads of q = ±1.4 e (in yellow), oriented along the monomer axis. Three arms originate from the central bead, which are composed of 5 CG-beads, linearly connected to form a three-armed monomer. The intra-molecule bonded interactions are modelled via harmonic bond and angle potentials, the parameters are reported in the SI. The core and arm CG beads interact via Lennard-Jones (LJ) potential: the interactions between the beads of the side-chains have ε = 1 kJ mol -1 and σ = 0.47 nm, the interactions between the side-chain and core beads have ε = 0.5 kJ mol -1 and σ = 0.47 nm, while ε = 2.5 kJ mol -1 and σ = 0.47 nm for the core-core interactions. The charged beads that determine the central dipole have no LJ interactions, and interact with each other electrostatically, imparting directionality to the monomer-monomer interaction. Complete details on the models and force field parameters used for the BTA monomer model are provided in the SI (in .GRO and .ITP GROMACS format).
