In 2014,Noguchi, Takao; Roy, Bappaditya; Yoshihara, Daisuke; Tsuchiya, Youichi; Yamamoto, Tatsuhiro; Shinkai, Seiji published 《Translation of Dicarboxylate Structural Information to Fluorometric Optical Signals through Self-Assembly of Guanidinium-Tethered Oligophenylenevinylene》.Chemistry – A European Journal published the findings.Computed Properties of C9H19NO4 The information in the text is summarized as follows:
Although self-assembly has realized the spontaneous formation of nanoarchitectures, the nanoscopic expression of chem. structural information at the mol. level can alternatively be regarded as a tool to translate mol. structural information with high precision. A newly developed guanidinium-tethered oligophenylenevinylene exhibits characteristic fluorescence (FL) responses toward L- and meso-tartarate, wherein the different self-assembly modes, termed J- or H-type aggregation, are directed according to the mol. information encoded as the chem. structure. This morphol. difference originates from the geometric anti vs. gauche conformational difference between L- and meso-tartarate. A similar morphol. difference can be reproduced with the geometric C=C bond difference between fumarate and maleate. In the present system, the dicarboxylate structural information is embodied in the inherent threshold concentration of the FL response, the signal-to-noise ratio, and the maximum FL wavelength. Self-assembly is meticulous enough to sense subtle differences in mol. information and thus demonstrate the potential ability of self-assembly for the expression of a FL sensory system. After reading the article, we found that the author used tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6Computed Properties of C9H19NO4)
tert-Butyl (2-(2-hydroxyethoxy)ethyl)carbamate(cas: 139115-91-6) 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. Computed Properties of C9H19NO4
