We report the synthesis and comprehensive characterization of organic-inorganic hybrid salts formed by bis-cationic N,N'- bis(2-(trimethylammonium)ethylene)perylene-3,4,9,10-tetracarboxylic acid bisimide (PTCD 2+ ) and Keggin-type [XW 12 O 40 ] n - (X = Si, n = 4; X = P, n = 3) polyoxometalates. (PTCD) 3 [PW 12 O 40 ] 2 ·3DMSO·2H 2 O ( 2 ) and (PTCD) 2 [SiW 12 O 40 ]·DMSO·2H 2 O ( 3 ) were structurally characterized by single crystal X-ray diffraction. The cations in both structures exhibited infinite chainlike arrangements through π-π interactions, contrasting with the previously reported cation-anion stacking observed in naphthalene diimide derivatives. A detailed theoretical study employing topological analysis of the electron density distribution within the quantum theory of atoms in molecules approach provided further insights into this structural dualism. Atomic force microscopy analyses revealed the formation of self-assembled supramolecular structures on graphite from molecular monolayers (3 nm of thick) to submicrometer aggregates for 2 . Hyperspectral Raman spectroscopy imaging revealed that such heterostructures are likely formed by an enhanced π-π interactions. Both complexes demonstrated interesting electrochemical behavior, photoluminescence and X-ray-induced luminescence. Electron spin resonance analysis confirmed charge separation in both compounds, with enhanced efficiency observed in compound 2 . Our findings of these perylene-based organic-inorganic hybrid salts offer the potential for their application in optoelectronic devices and functional materials. |
