Abstract: Stark gekoppelte, regio‐ und diastereomerenreine Subphthalocyanin‐C60‐Dyaden (siehe Kalottenmodell; B orange, C hellblau, H grau, N blau, O rot), die durch dreifache Addition erhalten wurden, können, abhängig vom Abstand zwischen den beiden komplementären π‐Oberflächen, auf Photoanregung unterschiedlich reagieren (mit Elektronen‐ oder mit Energietransfer).

“…56,58,59 Previous solution-phase studies of covalently linked SubPc-C 60 diads suggest that C 60 facilitates SubPc triplet formation through one or both of the pathways depicted in Figure 1a, where the predominant pathway depends on the polarity of the solvent environment and the electron-donating character of substituents on the SubPc. 18,44,52,60 This dependence on solvent polarity observed in diad solutions indicates that the local molecular environment may also affect the branching of kinetic processes in thin-film devices, altering populations of triplets, charge-transfer states, and free charge carriers.…”

“…66−68 Some of these factors, such as the dielectric environment, are known to alter the photophysics of triplet formation in solution-phase diads. 18,44,52,60 However, the additional influences in condensed films cannot be inferred from solution-phase measurements of covalently linked donor− acceptor pairs. Hence, the goal of this work is to investigate the influence of small-molecule aggregation on the kinetic processes relevant for photocurrent generation in solid-state devices.…”

“…Therefore light-harvesting antennae were attached to C 60 to enhance its absorption. [22][23][24][25][26][27][28][29][30][31] Previously, C 60 compounds with strong visible-light or panchromatic absorption have been prepared, but their triplet-state populations and photocatalytic properties have not been reported. [23][24][25][26] In this work, bodipy was selected as an antenna due to its versatile derivatization and satisfactory photophysical properties.…”
