Two novel tetraester- and PAMAM-branched perylene diimides were synthesized and configured as "fluorophore-spacer-receptor" systems based on photoinduced electron transfer. Due to their long alkylester and alkylamine terminal groups the examined compounds were well soluble in organic solvents. Photophysical characteristics of the dyes were investigated in DMF and water/DMF (1:1, v/v) solution. The ability of the synthesized perylene diimides to detect cations was evaluated by the changes in their fluorescence intensity in the presence of metal ions (Zn2+, Co2+, Cu2+, Fe3+, Pb2+, Hg2+, Ag+ and Ni 2+) and protons. The dyes under study displayed "off-on" switching in its fluorescence as a function of pH, which is attributed to disallowing photoinduced electron transfer from the receptor moiety to the fluorophore. PAMAM-branched dye displayed a good pH sensor activity (FE = 6.4), however the pH sensing ability of tetraester was substantially higher (FE = 184). In the presence of Cu2+ and Pb2+ ions tetraester quenched its fluorescence intensity (FQ = 22 and 12 respectively), while PAMAM-branched dye enhanced its fluorescence intensity with pronounced selectivity to Cu2+ and Fe3+ (FE = 3.2 and 4.9, respectively). The results obtained indicate the potential of the novel compounds as fluorescent detectors for metal ions with pronounced selectivity towards Cu2+, Pb2+ and Fe3+ ions and highly efficient "off-on" pH switches, especially a tetraester-branched perylene diimide.

experimental part, p. 29 - 38 (2011/08/02)
Three n-type polymers, Ppe01, Ppe02, and Ppe03, containing both perylene moieties and fluorine atoms were synthesized. The synthesiszed polymeric perylene derivatives with good compatibility for solution processes were chosen as new acceptor candidates fo

, p. 733 - 748 (2007/10/02)
The solid state fluorescence of diketopyrrolopyrrole dyes and perylene-3,4:9,10-tetracarboxylic bisimides with alkyl substituents are investigated and compared with noncovalent interactions.The latter are estimated by crystal structure analysis, heats and entropies of fusion and solubilities in organic solvents.Applications of the dyes are discussed.
