(A) Chemical structure of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and 1,2-dipalmitoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethylene glycol)-2000] (DPPE-PEG2000). (B) DPPC induces homeotropic alignment of 5CB at the aqueous-LC interface (left polarized light micrograph), while the same areal density of DPPC/DPPE-PEG2000 induces planar LC alignment (right polarized light micrograph). Grid size is 283 μm. Reproduced with permission from ref 67 (Royal Society of Chemistry).
