  • Title: Light harvesting and amplification of emission of donor perylene–acceptor perylene aggregates in aqueous medium.
    Author: Sukul PK, Datta A, Malik S.
    Journal: Chemistry; 2014 Mar 10; 20(11):3019-22. PubMed ID: 24677252.
    Abstract:
    With the aid of rational design, we have synthesized a pair of water-soluble donor- and acceptor-type twisted perylene bisimide units, which together form aggregates upon lowering the pH of the medium, providing bright yellow fluorescence. The light-harvesting efficiency of the co-assembled system can be tuned by controlling the ratio of donor to acceptor and 98.1 % efficiency has been achieved.
