Yu, Chuanming published the artcileNew photochromic dithienylethene based on porphyrin for a nondestructive information processing, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Pharma Chemica (2016), 8(22), 12-16, 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 can’t cause optical chem. reactions. Therefore, the data can be read out without damage.
Pharma Chemica 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 C9H21NO3, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene.
