n azobenzene amphiphile bearing perfluoro alkane chain (nPFHAZO) was synthesized. LB films with layer order periodic structure were fabricated. The nPFHAZO molecules in the LB films exhibited an excellent cistrans photoisomerization and thermoisomerization. The process is completely reversible. May be the perfluoro alkane chains afford adequate free volume for the isomerization in LB films.
