Resta, C.; Pescitelli, G.; Di Bari, L. published an article on January 31 ,2018. The article was titled 《Impact and amplification of chirality in the aggregation of leucine-appended poly(p-phenylene ethynylene) (PPE)》, and you may find the article in European Polymer Journal.Related Products of 74029-40-6 The information in the text is summarized as follows:
A leucine-appended poly(p-phenyleneethynylene) (PPE) was prepared in enantiomeric stereoregular (L-1 and D-1) and stereorandom (rac-1) forms. The solution aggregates of L-1, D-1, rac-1, and mixtures of L-1/D-1, were characterized by absorption, electronic CD and emission spectra. Both rac-1 and L-1/D-1 mixtures are more prone to aggregate than L-1 and D-1. Upon aggregating, the enantiomeric mixtures manifest an apparent majority-rules effect, which is mostly due to the greater tendency to form heterochiral aggregates with respect to homochiral ones. The impact of chirality on the aggregation behavior of the aminoacid-appended PPE is demonstrated. The experimental part of the paper was very detailed, including the reaction process of 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Related Products of 74029-40-6)
1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6) belongs to ethers. Ethers lack the hydroxyl groups of alcohols. Without the strongly polarized O―H bond, ether molecules cannot engage in hydrogen bonding with each other. Related Products of 74029-40-6
