- Fluorofluorescent Perylene Bisimides
-
Perfluorinated liquids can exhibit immiscibility with organic solvents and water, and provide orthogonal opportunities in chemistry. Examples of emissive dyes that display only fluorous phase solubility are limited, despite the many potential applications. Perylene bisimides are among the most versatile dyes and are known for their outstanding stability and high quantum yields. Herein, we report the synthesis of two new fluorofluorescent perylene bisimide dyes, designed to be soluble in the fluorous phases. These two dyes possess unique photophysical properties, including dramatic increases in fluorescence quantum yields when treated with Bronsted acids as well as aggregation in the fluorous phase.

- Synthesis and characterization of fluorescent dyes and their applications for the enhancement of growth rate of Chlorella vulgaris
-
Spectral conversion of solar radiation from green to red light can enhance the photosynthesis efficiency of microalgae. This can lead to significant increase in microalgal growth. Four perylene-based fluorescent dyes were synthesized to convert wavelengths of light from green (500–570 nm) to orange-red (580–650 nm). These dyes were applied in microalgal cultivation system using two methodologies: (1) light-converting layer, and (2) light-converting medium. The dyes were dissolved in either ethanol or water to form light-converting layers between microalgae culture and the light source. Under converted light in both set-ups, Chlorella vulgaris cultures showed maximum increase in lipid productivity by 13.00% and 17.15%, and biomass productivity by 31.65% and 37.66% compared to the control. Overall, the cultivation results confirmed beneficial effects of modified light on microalgae cultures both on their lipid and biomass productivities. Note that both growth parameters achieved higher performance in the light-converting medium thereby the effectiveness of the cultivation method was validated.

- The synthesis and characterisation of the perylene acid dye inks for digital textile printing
-
Five perylene acid dyes were synthesized to manufacture water-based inks for the high-speed ink jet printing process, including digital textile printing. All the synthesized perylene dyes exhibited superior stability and optical properties compared to a commercially used azo dye. Their water solubility was efficiently enhanced by introducing bulky and hydrophilic substituents to ensure excellent long-term stability when formulated as water-based inks. The water-based inks with these perylene dyes showed outstanding print clarity with the colours different from the basic colour composition of the existing digital textile printing inks. They also exhibited good ejection performance and helped conduct well-controlled pattern printing when used in a commercial ink jet printing machine.

- Perylenetetracarboxy-3,4:9,10-diimide derivatives with large two-photon absorption activity
-
Three new perylenetetracarboxy-3,4:9,10-diimides, bearing 2,6-diisopropylphenyl groups at the imide positions and 4-(R-ethynyl)phenoxy moieties (R = 4,7-di(2-thienyl)benzo[c][1,2,5]thiadiazole (P2), pyrene (P3) or pyrene-CH2OCH2 (P4)) at the four bay positions, were prepared, along with the known related derivative (R = phenyl (P1)), and well characterized. They have large two-photon absorption (TPA) cross-sections (σ2), as determined by the Z-scan technique, the highest values being reached with P2 which bears a planar π-delocalized donor moiety. P3 is characterized by higher σ2 values than both P1, as expected for the higher π-conjugation of the donor pyrene moiety with respect to phenyl, and P4, due to the presence of the flexible and non-conjugated CH2OCH2 bridge between the pyrene and the ethynyl fragment in the latter compound. The molecular geometry of P1-P4 has been optimized by DFT modeling, showing that in P2 and P3 the bay substituents are stacked due to the π-π interactions of both pyrene and thiophene groups. The LUMO of P1-P4 lies at the same energy and is essentially delocalized on the perylene core whereas the HOMO and HOMO?1 of both P2 and P3 are degenerate and do not show contribution from the perylene core contrarily to that of P1 and P4. The HOMO-LUMO gap is therefore essentially influenced by the HOMO which reflects the electronic charge delocalization on the bay substituents, the lower gaps being observed for P2 and P3, which are characterized by the best TPA properties.

- Energy transfer in pendant perylene diimide copolymers
-
We report the synthesis, characterisation and polymerisation of two novel asymmetric perylene diimide acrylate monomers. The novel monomers form a sensitiser-acceptor pair capable of undergoing F?rster resonance energy transfer, and were incorporated as copolymers with tert-butyl acrylate. The tert-butyl acrylate units act as spacers along the polymer chain allowing high concentrations of dye while mitigating aggregate quenching, leading to persistent fluorescence in the solid state at high concentrations of up to 0.3 M. Analysis of fluorescence kinetics showed efficient energy transfer between the optically dense sensitiser and the lower concentration acceptor luminophores within the polymer. This reduced reabsorption within the material demonstrates that the copolymer-scaffold energy transfer system has potential for use in luminescent solar concentrators.
