摘要. Expanded porphyrins are attractive molecules in terms of aromaticity, metal complexation, optical properties and supramolecular chemistry. This seminar presents our recent progress on the novel hybrid expanded porphyrinoid------cyclo[m]pyridine[n]pyrroles. Through the six-membered macrocycles, we have been able to manipulate the aromaticity/antiaromaticity by means of protonation or metallation (deprotonation); we can also realize a stable aromatic radical. These macrocycles, interacting with various organic diacids, generate chemical-responsive supramolecular polymers which can differentiate various organic solvents and anions. The higher congener of such macrocycles owns a flexible structure and displays various conformations under different environments. These novel macrocycles represent a promising family of porphyrinoids that have diverse structures and are useful for supramolecular sensing.
