Abstract
Columnar stacks of N,N'-di(2-(trimethylammoniumiodide)ethylene) perylenediimide (TAIPDI) n can host meso-tetrakis(4-sulfonatophenyl) porphyrin zinc tetrapotassium salt (ZnTPPSK 4) molecules at different ratios through the ionic and π-π interactions prompted by an aqueous environment. Photoexcitation of this host-guest complex generates very fast charge separation (1.4 × 10 12 s -1). Charge recombination is markedly decelerated by a probable electron delocalization mechanism along the long-range of tightly stacked TAIPDIs (4.6 × 10 8 s -1), giving an exceptional k CS/k CR ratio of 3000 as determined by using time-resolved transient absorption techniques. © 2012 American Chemical Society.
