From Porphyrin Chemical Dimers to Complex Multicomponent Nanoassemblies: Some Rare Phenomena and Relaxation Processes

“…Within the German-Belarus scientific cooperation we have realized a simple and yet potentially versatile strategy for the formation of highly organized and relatively rigid multimolecular tetrapyrrole nanoassemblies based on the combination of covalent linkage and non-covalent interactions in solutions and polymeric (PMMA) films. [56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71] The first step presents itself as a covalent stage, where precursor molecular blocks such as Zn porphyrin or Zn chlorin chemical homo-or heterodimers with a covalent linkage of various nature (-CH 2 -CH 2 -or a phenyl ring in mesoposition) as well as chemical trimers of Zn octaethylporphyrins with phenyl spacers in meso-positions were synthesized. Additionally, various types of electron acceptors (quinone, anthraquinone, pyrromellitimide, NO 2 group) could be covalently linked to these dimers by flexible or rigid spacers.…”
