It was found that 3,3'-, 2,3'- and 2,2'-zinc(II) bis(dipyrromethenate)s ([Zn2L2]) form stable supramolecular complexes with aromatic and aliphatic amines (X - pyridine (Py), N,N-dimethylmethanamide (DMF), diethylamine (DEA) and triethylamine (TEA)) of the composition [Zn2L2(X)(n)]. Composition, stability and spectral-luminescent properties of the [Zn2L2(X)(n)] crystal solvates were studied by means of MR, PXRD, thermal, mass spectral, absorption, and fluorescence analyses. Spectroscopic studies showed that the quantum yield (phi) of [Zn2L2(X)(n)] in cyclohexane is much lower (to similar to 1.4-4.0 times) than phi for the [Zn2L2]. Crystal solvates are stable up to a temperature similar to 367.35-427.55 K. It is demonstrated, that the high interactions energies (Zn-N) in [Zn2L2(X)(n)] supramolecular complexes are the main cause of the fluorescence quenching of [Zn2L2] luminophores in the presence of electron-donor molecules. The obtained results are of interest for the development on the basis of [Zn2L2] of a new fluorescent sensors of the electron donor molecules.
