Abstract
Giant p-(R)calixarenes, a process for the preparation of giant p-(R)calixarenes with high yields, and their use as the constitution of a material or in the context of the reinforcement of the material.
Claims10
Mixture of calixarenes of the following formula (IV):
- in which n is an integer comprised from 21 to at most 220, and in which R is selected from the group consisting of:
- a benzyloxy group optionally substituted in the ortho and/or para and/or meta position with one or more substituents selected from a halogen, SR′ and OR′, R′ representing a linear or branched C1-C20 alkyl chain, a C3 to C20 cycloalkyl group, NRaRb, PRaRb, P(O)RaRb, P(O)ORaORb, Ra and Rb representing, independently of one another, a linear or branched C1-C20 alkyl,
- a linear or branched C1-C20 alkyloxy group, a linear or branched PEG-1 to 10, the —OH end group of which is alkylated with a linear or branched C1-C20 alkyl,
- a benzyl thioether group —S—CH2-Ph optionally substituted in the ortho and/or para and/or meta position with one or more substituents selected from a halogen, SR′ and OR′, NRaRb, PRaRb, P(O)RaRb, P(O)ORaORb, Ra and Rb representing, independently of one another, a linear or branched C1-C20 alkyl,
- a linear or branched C1-C20 alkyl thioether group, of formula —S—(C1-C20-alkyl),
- an —NRaRb group, Ra and Rb representing, independently of one another, a linear or branched C1-C20 alkyl, and
- a dibenzylamine group of formula —N(benzyl)2, in which the two benzyl groups are, independently of one another, optionally substituted in the ortho and/or para and/or meta position with one or more substituents selected from a halogen, SR′ and OR′, R′ representing a linear or branched C1-C20 alkyl chain, a C3 to C20 cycloalkyl group, NRaRb, PRaRb, P(O)RaRb, P(O)ORaORb, Ra and Rb representing, independently of one another, a linear or branched C1-C20 alkyl.
