Synthesis of huge macrocycles using two calix[4]arenes as templates.

چکیده
Macrocycles with up to 100 atoms have been synthesised using two calix[4]arenes as templates: first, (3,5-dialkenyloxy)phenyl groups are attached to the wide rim of a calix[4]arene via urea links, then the alkenyl groups are connected via a metathesis reaction using a tetratosylurea calix[4]arene for their correct prearrangement and finally the urea functions are cleaved to detach the newly formed macrocycles.

Calixarenes with naphthalene units: calix[4]naphthalenes and hybrid[4]arenes
Macrocycles consisting of naphthalene units connected via methylene bridges offer certain advantages as macrocylic scaffolds as compared with parent calixarenes. These advantages originate from their electron rich and enlarged cavities. Additionally, macrocycles containing 1,3-bridged naphthalene units are dissymmetric and therefore they present interesting stereochemical features, including in...

Up to now, various empty carbon fullerenes with different magic number "n", such as C10, Cow Cm, Cso,Cis** Cm and so on. have been obtained. The calix[n]arenes are a class of chalice-like rnacrocyclicmolecules that have attracted widespread attention as complex molecules with liquid crystal behaviors.These classes of compounds are cyclic ohgomers synthessid by condensation of a para-alkylated p...
متن کاملPd-induced ordering of 2D Pt nanoarrays on phosphonated calix[4]arenes stabilised graphenes.
p-Phosphonic acid calix[4]arenes render high stability to exfoliated graphenes in water. These calix[4]arenes modified graphenes can be used as highly effective substrates to nucleate ultra-small Pd nanoparticles, which in turn serve as galvanic reaction templates for the generation of high density 2D arrays of Pt nanoparticles.
متن کاملSynthesis and capsule formation of upper rim substituted tetra-acrylamido calix[4]arenes.
Upper rim substituted tetraiodo calix[4]arenes are coupled to a variety of acrylamides using the palladium catalysed Heck reaction. Tetra-acrylamido upper rim substituted calix[4]arenes are obtained in good yields with exceptionally high stereoselectivity, to produce the all-trans isomers. Tetra-acrylamido calix[4]arenes derived from secondary acrylamides are shown to dimerise via eight hydroge...
