Bending a Photonic Wire into a Ring.
Nat. Chem. 2022;
14: 1436-1442
Key words
porphyrin array - electronic excitation - energy transfer - nanoring
Significance
Cyclic chromophore arrays mimicking chlorophylls in the natural photosynthetic system capable of absorbing sunlight and funneling photon energy are particularly attractive goals.
Comment
Linear porphyrin chains that effectively transfer electronic excitation energy were previously reported, and now a giant macrocycle analogue comprising of 24 porphyrin units is accomplished.
