The synthesis and character of novel organic photochromic diarylethenes, 1,2-bis (2-methyl-5-(4-(2-(1,3-dioxacyclohex)benzene)thiophen 3-yl) perfluorocyclopentene (1a) and 1,2-bis(2-methyl-5-(4-benzaldehyde)thiophen 3-yl) perfluorocyclopentene (1a′) are studied. These two diarylethenes are mixed with polymethyl methacrylate (PMMA) respectively to coat the substrates by the spin-coating, and then applied to near-field recording by the solid immerse lens (SIL) as well. The size of recording spot is under 1 μm.
