Crystal structures and solid-state emission properties of tetraalkyl 4,4′-dimethyl-2,2′-bipyrrole-3,3′,5,5′-tetracarboxylates (alkyl = methyl, ethyl, and isopropyl) have been investigated. Single crystal X-ray diffraction studies revealed that all bipyrroles are co-planar due to an intramolecular hydrogen bonding. The isopropyl derivative exhibited a C=O·π interaction in the solid-state and showed the longest emission wavelength because of increase in structural flexibility.
