- Example sentences
- Their device was based on a supramolecular system consisting of a p-electron-donating macrocycle threaded with a p-electron-accepting wire-like molecule.
- Very few porphyrins are known to form J-aggregates, the main requisite being the zwitterionic character with the protonation of the pyrrole nitrogen in the macrocycle.
- However, similar spectral changes can also be produced by the protonation of the macrocycle at the azomethine nitrogens, although there are very few reports in which this phenomenon is discussed.
