title: Self-assembled cyclic boron-dipyrrin oligomers.
abstract: Self-assembled cyclic boron-dipyrrin oligomers 3-5 obtained by the reaction of catecholyldipyrrin with boron trichloride were characterized by 1H NMR, MALDI-TOF MS, and X-ray measurements and the interaction between 3 and alkali metal ions was examined.
