Supramolecular organization of asymmetrical phthalocyanine derivatives in bulk samples and floating layers
Features of floating layers and Langmuir-Blodgett films formed by three asymmetrical phthalocyanine derivatives with 3,6-dioctyloxyphthalonitrilie and 3,4,5,6-tetrachloro-phthalonitrile parts were studied. Comparison of absorption spectra of these compounds in thin films and solutions in chloroform allows to argue that the compounds exhibit higher association tendency in thin films than in solutions. Computer simulation study of phthalocyanine derivatives in bulk samples over a wide temperature range, corresponding to their different phase states u sing the molecular dynamics method on modern graphics controllers was carried out. It is established that the results of computer simulation have a good agreement with the results of previously performed polarizing optical microscopy investigation, which makes the described method suitable for a direct design of new compounds or systems with the desired properties.
