Ion-pair Receptors Flashcards
1
Q
What are the three types of ion-pair receptors?
A
Cascade complexes
Receptors with individual cation and anion binding sites
Receptors for zwitterionic guests
2
Q
How do cascade complexes work?
A
Receptor binds more than one metal cation in well defined locations. These ‘recruited’ cations then interact with an anionic guest
3
Q
What are the two types of receptors with individual cation and anion binding sites?
A
Non-contact
Contact
4
Q
What is cooperative behaviour?
A
If ion added, this causes a change of conformation which allows a second ion to be added
