a, b Charge density difference (\(\triangle {\rm{\rho }}={\rm{\rho }}\left({\rm{FGT}}+{\rm{TBA}}\right)-{\rm{\rho }}\left({\rm{FGT}}\right)-{\rm{\rho }}({\rm{TBA}})\), where \({\rm{\rho }}\left({\rm{FGT}}+{\rm{TBA}}\right)\) is the total charge density of FGT plus TBA, \({\rm{\rho }}\left({\rm{FGT}}\right)\) is the charge density of the isolated FGT system, and \({\rm{\rho }}({\rm{TBA}})\) is the charge density of the TBA molecules) through iso-surface and planar average along the z direction, respectively. In a, green and blue iso-surfaces correspond to positive and negative charge, respectively.
