“…1% of the film surface. In view of the drastic inhomogeneity of fullerene composites, ,,, such a surface seems practically uniform, indicating that the CoPc # –C 60 system is highly resistant to the phase separation. Besides, there is a network of artificial grooves caused by a shear stress applied to the film during deposition.…”

Random mixtures of phthalocyanines (Pcs) with fullerene C 60 are currently exploited as active layers in organic solar cells. Therefore, spatially regular Pc−C 60 heterostructures, not designed so far, are of great interest as molecularly mixed donor−acceptor phases for further improving the device performance. Here we investigate the prospects to create such heterostructures by fine intermixing of π-rich Pcs with fullerene C 60 . Specifically, this work reports on the mixing behavior of cobalt tetrakis(3-amino-5-tert-butyl)phthalocyanine (CoPc # ) with fullerene C 60 . A composite film (CoPc # /C 60 = 1:2, mol) was prepared by the Langmuir−Schaefer technique from a floating layer with doubledecker architecture, where the CoPc # monolayer was interlinked with the C 60 submonolayer by the clustered water. This film was structurally analyzed and compared with the CoPc # film used as a reference. The latter film is found to be constructed from the 2-stack dye aggregates, which are assembled in the χ-phase mode, randomly oriented, and loosely packed. In the composite film, the C 60 molecules tend to intercalate into the interaggregate voids, making the aggregates consolidate and align in the vertical direction. Accordingly, the delamination process, which freely occurs in the pristine dye film, is inhibited in the composite. All aggregative features of CoPc # indicate that both structure and arrangement of the dye aggregates are determined by water-assisted H bonding via the primary amine groups. This kind of interaction is of use for tailoring Pc-based frameworks capable to host the C 60 molecules.

Thermochemical Insights into Fullerene Aggregation and the Phthalocyanine–Fullerene Interaction in Efficient Solvents

The physicochemical behavior of fullerene C in hydrocarbon solvents is examined by isothermal titration calorimetry, photocalorimetry, and UV spectroscopy. The obtained data are summarized to substantiate the idea of the binary fullerene/solvent cluster as a colloidal nanoentity that moderates noncovalent interactions of the C molecule in solution. This idea serves to aid understanding of the complex physicochemical behavior of tert-butyl-substituted phthalocyanine in C -saturated o-xylene under illumination with low-energy photons. The proposed experimental approach, which focuses on concentrated solutions and is applicable to multicomponent systems, is discussed as a potential tool of materials science.
