A new thermally reversible photochromic compound, 4′,5′-hexafluoropropano-6′-phenylspiro[adamantane-2,7′(6′H)-benzothiophene], derived from UV-irradiation of 2-(1-adamantylidene-1-phenylmethyl)-3,3,4,4,5,5-hexafluoro-1-(3-thienyl)cyclopentene via the photochemical 6π-electrocyclization followed by the thermal 1,5-hydrogen migration, was synthesized and its photochemical and thermal properties were
一种新的热可逆光致变色化合物,4',5'-六氟丙烷-6'-苯基螺[金刚烷-2,7'(6'H)-苯并噻吩],衍生自 2-(1-adamantylidene-1-)苯甲基)-3,3,4,4,5,5-六氟-1-(3-噻吩基)环戊烯通过光化学6π-电环化和1,5-氢热迁移合成,并具有光化学和热性能被审查。结构更简化的 3,3,4,4,5,5-六氟-2-(2-methyl-1-phenyl-1-propenyl)-1-(3-thienyl)cyclopentene 没有产生热可逆光致变色化合物在紫外线照射下。
