Dual molecular tweezers extending from a nanohoop

The field of nanohoops is mature enough that synthetic protocols exists to tune their size, composition (incorporation of heteroaromatic building blocks), connectivity ( para versus meta linkages), and solubility in different media (hydrophobic versus hydrophilic). Here, we report an additional dime...

Description
Summary:The field of nanohoops is mature enough that synthetic protocols exists to tune their size, composition (incorporation of heteroaromatic building blocks), connectivity ( para versus meta linkages), and solubility in different media (hydrophobic versus hydrophilic). Here, we report an additional dimension incorporating the concept of fullerene tweezers into a nanohoop. The resulting hybrid nanohoop is highly strained at 77 kcal mol −1 , possesses a quantum yield of 0.12, emits at 584 nm, and displays a positive cooperative binding for C 60 (4 K 2 > K 1 ). Merging ideas of fullerene tweezers and nanohoops.
