The dimeric association of α,α′-di(benzylamino)tripyrrin in chloroform was found to be 40 times less effective than that of previously reported α,α′-dianilinotripyrrin, which, however, led us to observe the co-crystal structure of single and double helix forms. Attachment of chiral phenylethylamines on the same tripyrrin platform was also performed to induce helical chirality.
