Cavitand zn(II)-porphyrin capsules with high affinities for pyridines and N-methylimidazole.
Covalent cavitand Zn(II)-porphyrins 17-20 were prepared via multistep syntheses. These host molecules show moderate to excellent binding affinities to N-methylimidazole and pyridine guests. The complexing behavior strongly depends on the spacer's length, number, and rigidity, in addition to the guest size. Cavitand capping and strapping of porphyrins strongly influence the complex formation and...

The reaction of tetra-kis-(all-yloxy)calix[4]arene with the first-generation Grubbs catalyst, followed by catalytic hydrogenation, gave the novel bis-calixarene 15,20,46,51,64,69,74,79-octa-oxatridecacyclo[32.28.8.8(3,28).1(13,53).1(22,44).0(9,14).0(21,26).0(38,70).0(40,45).0(52,57).0(59,63).0(7,80).0(32,73)]octa-conta-1(63),3,5,7(80),9(14),10,12,21,23,25,28(73),29,31,34,36,38(70),40,42,44,52,5...
متن کاملGold nanoparticles: calixarene complexation in a mixed calixarene–alkanethiol monolayer†
This paper describes a detailed study on the complexation of pyridinium derivatives with calixarenes bound to gold nanoparticles (AuNPs). The studied calixarene derivatives are mixed with alkanethiols to formmixed monolayers on AuNP surfaces. The key findings are: (i) even a small amount (less than 11 mol%) of calixarenes can retain their complexation abilities among a majority of alkanethiols ...
