•Novel planar binuclear porphyrazines based on a 3,4-thiophene moiety were synthesized.•All thiophene units of the porphyrazine periphery are equivalent.•Spectral properties and aggregation phenomena of the target compounds were investigated by UV-Vis spectroscopy and AFM.•On the basis of MCD data the absorption maxima in the Q band region were assigned.
The first examples of planar binuclear porphyrazines sharing a common benzene or naphthalene ring based on a 3,4-thiophene moiety have been synthesized and characterized using nuclear magnetic resonance spectroscopy, high-resolution mass spectrometry, electronic absorption spectroscopy and magnetic circular dichroism. In order to enhance the interpretation of the electronic structures, quantum chemical studies were carried out. The formation of nanoaggregates in a solid film was shown using atomic force microscopy.
