Benzyl benzodithioate (cas: 27249-90-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Name: Benzyl benzodithioate
Tryptophan-Containing Block Copolymers Prepared by RAFT Polymerization: Synthesis, Self-Assembly, and Chiroptical and Sensing Properties was written by Mori, Hideharu;Takahashi, Eri;Ishizuki, Ai;Nakabayashi, Kazuhiro. And the article was included in Macromolecules (Washington, DC, United States) in 2013.Name: Benzyl benzodithioate This article mentions the following:
Novel tryptophan-based block copolymers with unique self-assembled structures, chiroptical properties, and sensing functionality were synthesized by reversible addition-fragmentation chain transfer (RAFT) polymerization of a tryptophan-containing acrylamide, N-acryloyl-L-tryptophan (A-Trp-OH). Polymerization of A-Trp-OH using a suitable chain transfer agent (CTA) proceeded in a controlled fashion, as confirmed by the relatively narrow polydispersity of the products and a mol. weight that could be controlled by the monomer-to-CTA molar ratio. Hydrophilic polymers obtained by RAFT polymerization of N,N-dimethylacrylamide, poly(ethylene glycol) Me ester methacrylate, and N-acryloyl-4-trans-hydroxy-L-proline were used as macro-CTAs. Chain extension of these hydrophilic macro-CTAs with A-Trp-OH was well controlled under the appropriate conditions to afford block copolymers with “as-designed” chain structures and relatively low polydispersities. The formation of micelles consisting of a hydrophobic core of poly(A-Trp-OH) and a hydrophilic shell was observed in aqueous solution and affected the optoelectronic properties of the polymer. We further investigated the chiroptical and sensing properties of the block copolymers by dynamic light scattering, UV-vis and fluorescence spectroscopy, and CD measurements. We present a new example of amino acid-based polymeric fluoride ion (F–) probes in which micelles self-assembled from these block copolymers serve as enhanced ratiometric fluorescent and chiroptical F– sensors, possessing characteristic detection capabilities in aqueous and organic media. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7Name: Benzyl benzodithioate).
