New class of clamshell-type lanthanide (Ce(IV), La(III) and Eu(III)) diphthalocyaninates bearing 24-crown-8 linking fragment are synthesized and characterized by means of NMR, UV-vis spectroscopies and MALDI-TOF mass spectrometry. A strong solvatochromism of the complexes, allowing switching the wide-range panchromatic absorption in polar solvents, is demonstrated by means of UV-vis and NMR spectroscopies and attributed to solvent-induced changing of sandwich conformations. The photodegradation of the obtained complexes was also investigated.
