Charge-separation in panchromatic, vertically positioned bis(donor styryl)BODIPY–aluminum(iii) porphyrin–fullerene supramolecular triads

Abstract

Three, broad band capturing, vertically aligned reaction center models have been constructed using aluminum(iii) porphyrin.

Does Location of BF2-Chelated Dipyrromethene (BODIPY) Ring Functionalization Affect Spectral and Electron Transfer Properties? Studies on α-, β-, and Meso-Functionalized BODIPY-Derived Donor–Acceptor Dyads and Triads

“…In recent years, our groups have explored various antenna−donor−acceptor model compounds possessing BODIPY as one of the active components. [18][19][20][21][22][23][24][25][26]37,38 In the majority of the studies where BODIPY formed part of the donor−acceptor system, the functionalization was carried out at the meso-position. 18−26,29−36 Only a handful of studies utilized the pyrrole α and β positions.…”

Quantitative insights into charge-separated states from one- and two-pulse laser experiments relevant for artificial photosynthesis

“…Encouraged by the efficiency of natural photosynthesis,1 numerous research groups have focused on mimicking its key steps. In particular, a great many studies explored molecular donor–acceptor compounds,2–27 in which the primary photoinduced charge separation was frequently enabled by a covalently linked photosensitizer 5,6,10–16,19,24. Optimizing the primary charge separation is without any doubt one basic requirement for the realization of much more complex artificial systems allowing solar fuel production through multiphoton-driven charge accumulation 28–31.…”

[28][29][30][31] However, the great majority of previous studies on charge-separated states merely investigated their qualitative formation aer light absorption and their lifetimes, but systematic quantum yield investigations 12,14,32 are scarce.…”

Photoinduced electron transfer and unusual environmental effects in fullerene–Zn-porphyrin–BODIPY triads

“…4,[33][34][35][36][37] Taking into account that in natural photosynthetic systems the chlorophylls are linked to the protein via axial ligation, much attention was paid to systems where donor and acceptor subunits are axially arranged. [38][39][40][41][42] Systems where donor and acceptor are located linearly 5,34,[43][44][45] (in the plane of porphyrin) or V-shaped are also known. [46][47][48] In porphyrin-BODIPY arrays, the both fragments complement each other.…”
