AbstractBoth bulk and boundary orientations, and boundary shape equations for tilted lipid domain are derived in analogy with a polar cholesteric liquid crystal. It shows that in a two-dimensional (2D) system the 3D spontaneous splay and chiral elastic energies, the s(0) and q(0) terms of Frank energy, can be regarded as an orientation-dependent line tension, and the domain formation is the equilibrium between the line tension, the surface pressure, the orientational stress, and the dipole-dipole interaction. An obvious and analytic shape solution for pinned boundary orientation for maximum boundary tension has been found and the diverse domain shapes observed in lipid monolayers in the past two decades, such as star, boojum, cardioid, ellipse, bola, and clover-leaf shapes, are dramatically well described by the solution.
