《Chiral Cd(II) Coordination Polymers Based on Amino Acid Derivatives: The Effect of Side Chain on Structure》 was published in Crystal Growth & Design in 2020. These research results belong to Tay, Hui Min; Hua, Carol. HPLC of Formula: 7524-52-9 The article mentions the following:
Homochiral coordination polymers have emerged as promising candidates for a range of chirotechnol. applications, including asym. catalysis and enantioselective separation The use of ligands derived from naturally occurring L-amino acids is an inexpensive and effective approach for generating a range of homochiral coordination polymers. To investigate the structure-directing effect of the amino acid side chain, seven homochiral Cd(II) frameworks were synthesized using semirigid dicarboxylates composed of L-amino acids appended to terephthalic acid (H2TMXxx, where Xxx = Ala, Val, Phe, Trp, Tyr, and His) and bis(4-pyridyl)ethylene coligands. When Xxx = Val, Tyr, Phe, or Trp, a series of 2D (4,4)-networks were obtained, in which the different intermol. interactions of the side chains result in subtle changes in crystal packing. Employing Xxx = Ala or Tyr led to 3D frameworks with a {65·8} topol., in which the varying steric bulk of the side chains results in significant differences in framework geometry as well as the shape and volume of the solvent-accessible channels. When Xxx = His, the imidazole side chains coordinate to the metal center to direct the formation of a 3D pillared structure that undergoes 2-fold interpenetration. In the experiment, the researchers used H-Trp-OMe.HCl(cas: 7524-52-9HPLC of Formula: 7524-52-9)
H-Trp-OMe.HCl(cas:7524-52-9) is one of amino acid derivatives. Amino acid derivatives represent an important category of skin penetration promoters. These compounds possess hydrophobic chains attached to an amino acid headgroup via a biodegradable ester bond. Due to the amphiphilic nature of these derivatives, it is possible for them to enter into the SC lipid barrier and significantly disorganize skin membrane lipids.HPLC of Formula: 7524-52-9
