Synthesis of new 1,3,5-tris-styryl-benzene compounds with tunable photo- and electroluminescent properties was written by Behnisch, B.;Hanack, M.. And the article was included in Synthetic Metals in 2001.Application of 16144-65-3 The following contents are mentioned in the article:
A series of 1,3,5-tris-styryl-benzene dendrimers was obtained via Knoevenagel reaction of a 1,3,5-tris-cyanomethylene benzene derivative with substituted benzaldehydes. The synthesis starting from mesitylene, followed by bromomethylation or NBS-bromination, bromo-cyano exchange, and a threefold condensation reaction leads to a conjugated system with different optical properties, depending on the substituent in the p-position (alkyl, alkoxy, amino). The photo- and electro-luminescent properties of the styryl-benzene dendrimers were studied. The addnl. Me groups at the central ring generate steric hindrance that is reflected in a strong hypsochromic shift in the UV absorption spectrum, compared to the unsubstituted analog. The series of π-conjugated dendrimers with substituent-based tunable luminescence are of interest for use in LEDs. This study involved multiple reactions and reactants, such as 2,2′,2”-(2,4,6-Trimethylbenzene-1,3,5-triyl)triacetonitrile (cas: 16144-65-3Application of 16144-65-3).
2,2′,2”-(2,4,6-Trimethylbenzene-1,3,5-triyl)triacetonitrile (cas: 16144-65-3) belongs to nitriles. There has been no report on the microbial biosynthesis of nitriles and the physiological function of such enzymes, nor was it not even known whether aliphatic and aromatic nitriles are biological compounds or just petrochemicals. Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. Both routes are green in the sense that they do not generate stoichiometric amounts of salts.Application of 16144-65-3
