Yu, Chuanming published the artcileNew photochromic dithienylethene based on porphyrin for a nondestructive information processing, Formula: C15H14Cl2S2, the publication is Archives of Applied Science Research (2016), 8(12), 18-23, database is CAplus.
A new 1-[2-methyl-5-(4-tetraphenylporphyrinphenyl)-3-thienyl]-2-[2-methyl-3-thienyl]-cyclopentene (DTE-TPP) combined by 3,3-(1-Cyclopentene-1,2-diyl)bis(5-chloro-2-methylthiophene) (DTE) and tetraphenylporphyrin (TPP) can transform between the open isomer and the closed isomer upon the irradiation of UV or visible light. Herein, they can be used to write binary data. Furthermore, the open form can emit luminescence but the closed cannot while irradiated in another light that cant cause optical chem. reactions. Therefore, the data can be read out without damage.
Archives of Applied Science Research published new progress about 219537-97-0. 219537-97-0 belongs to chlorides-buliding-blocks, auxiliary class Fused/Partially Saturated Cycles,Cyclopentenes, name is 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, and the molecular formula is C10H25NO2Si, Formula: C15H14Cl2S2.
