Two lysosome-targeting fluorescent anion transporters derived from coumarins, trifluoromethylated arylsquaramides and morpholines were synthesized, and their specificity and efficiency to target and alkalize lysosomes were investigated. They are able to target lysosomes specifically. Compared with the previous analogue without trifluoromethyl substituents, these two conjugates, in particular the one

Two tripodal squaramide conjugates having 4-(trifluoromethyl)phenyl and 3,5-bis(trifluoromethyl)phenyl substituents were synthesized and found to exhibit highly efficient transmembraneanion transport with the EC50 values being 0.14 and 0.75mol%, respectively. Though one of them has been reported to act as a strong anion receptor, in particular for sulfate anions, these two compounds exhibit no significant

Squaramide-based tripodal anionreceptors have been prepared and their anion binding properties with various inorganic anions were investigated. Receptor formed a dimeric complex in solid state and a 1 : 1 complex in solution with SO(4)(2-). All receptors could selectively encapsulate SO(4)(2-)via hydrogen bonds over other examined anions.
