The low-angle ∧-shaped molecule based on 1,7-naphthalene central core and long side-chain with alkylthio tails were synthesized. The mesomorphic properties and phase structures were investigated by means of polarized optical microscope and wide angle X-ray diffraction with non-oriented and oriented samples. The compound can form an Iso-SmAP-B4 transition with a layer spacing of 51.4 ? in SmAP phase during the cooling process. The introduction of low-angle ∧-shaped central core and long-side chain with alkylthio tails are considered to be vital for the formation of this type of molecular assembly.
