摘要：
A new photochromic diarylethene, [1-(2-methyl-5-(4-cyanophenyl)-3-thienyl-2-(2-methyl-5-phenyl-3-thienyl)]perfluorocyclopentene (1o, C28H17F6NS2), was synthesized and its structure was determined by single-crystal X-ray diffraction analysis. Its crystal belongs to the monoclinic system, space group P2(1)/c with a = 24.1381(5), b = 9.3834(6), c = 11.1073(8), beta = 94.477(4)degrees, Z= 4, V= 2508.1(3) angstrom(3), D-c = 1.445 mg/m(3), mu = 0.275, F(000) = 1112, the final R = 0.0482 and wR = 0.1429 for 5834 observed reflections (I> 2 sigma(I)). Further study demonstrated the diarylethene underwent reversible photochromism, changing between colorless and blue in hexane solution, crystalline phase and PMMA films, respectively.
