Phosphine oxide-functionalized polyfluorene derivatives: Synthesis, photophysics, electrochemical properties, and electroluminescence performance

A series of phosphine oxide-functionalized polyfluorene derivatives, PFH-PO-40-1 (P1), PFH-PO-20-1 (P2), PFH-PO-10-1 (P3), and PFH-PO-1-1 (P4), were prepared via a palladium-mediated Suzuki cross-coupling reaction. The structures and purities of all polymers were fully characterized by 1H and 13C NMR, UV-vis and photoluminescent spectroscopy, gel permeation chromatography, and TGA/DSC. Their emission features showed single broad peaks at about 445 nm in film, compared with those in dilute solutions, which might be caused by some degree of aggregation in the excited states of the backbones. The best electroluminescence (EL) performance of these polymers with configuration of ITO/PEDOT:PSS/Polymer/Alq3/LiF/Al was obtained from P1 (current efficiency was 4.2 Cd/A at 6V).

Polytellurophenes with properties controlled by tellurium-coordination

Coordinated control: Owing to their numerous synthetic challenges, polytellurophenes are a virtually unexplored class of conjugated polymers. A new dihalogenated bitellurophene monomer has been synthesized and its polymerization under palladium-catalyzed conditions was optimized. The resulting polytellurophenes are stable compounds with distinct optoelectronic properties that can be controlled by coordination with bromine (see picture). Copyright

CdSe/ZnS Nanoparticle composites with amine-functionalized polyfluorene derivatives for polymeric light-emitting diodes: synthesis, photophysical properties, and the electroluminescent performance

A series of amine-functionalized poly(9,9-dihexylfluorene) (PFH) derivatives, PFH-NH2F39-1 (P1), PFH-NH2F-19-1 (P2), PFH-NH2F-9-1 (P3), and PFH-NH2F-17-3 (P4), and PFH-NH 2F-4-1 (P5), were developed to form organic/inorganic hybrid composites with CdSe/ZnS nanoparticle for polymeric light-emitting diodes (LEDs). The structures and purities of all desired polymers were fully characterized by 1H and 13C NMR, UV-vis and photoluminescent spectroscopy, gel permeation chromatography, elemental analyses. The hybrid nanocomposites were in situ formed through these amino-functionalized polyfluorene derivatives doped with core-shell CdSe/ZnS quantum dots (QDs). The detailed characterizations of their photophysical properties revealed that rapid Foerster energy transfer from the conjugated polymers to the redemitting QDs afforded an efficient red color emission. The preliminary polymeric LEDs fabrication with the configuration of ITO/DB/nanocomposites/Al achieved red emission for the in situ prepared hybrid nanocomposites. The investigation of device performance indicates that these nanocomposites are promising red light-emitting polymeric LED materials with good performance in providing excellent color purity, stability, and robustness. Such strategy provides us a platform to achieve red-emitting hybrid nanocomposites as the active materials for LEDs.

Molecular Weight Engineering in High-Performance Ambipolar Emissive Mesopolymers

Mesopolymers with high solubility, free of structural defects, and negligible batch-to-batch variation open a new avenue for organic optoelectronics. Organic light emitting transistors that combine the functions of organic light-emitting diodes and organic field-effect transistors. However, charge transport ability and light emitting strength are contradictory within one conjugated polymer. Herein, three low-molecular-weight mesopolymers with thienopyrroledione–benzothiadiazole repeating units (meso-TBTF) were obtained. The mesopolymers show strong solid-state emission and high ambipolar carrier mobility. The molecular weights of meso-TBTF can be tuned by polymerization temperature. The mesopolymers have photoluminescence quantum yields (PLQY) of about 50 % in solution and 10 % in solid state. Polymer light emitting diodes of this material are fabricated to explore its potential use in optoelectronic devices.

An ultra-highly sensitive and selective self-enhanced AIECL sensor for public security early warning in a nuclear emergencyviaa co-reactive group poisoning mechanism

The worldwide application of nuclear power has created the potential risk of a nuclear accident, which has been a challenge to public security. In nuclear leakages, I2radioisotopes would cause rapid, global pollution. Therefore, highly sensitive and selective I2sensors exhibit their significance in nuclear accident early warnings and treatments. Herein, a conjugated polymer was developed for I2vapor monitoring with an ultra-low limit of detection (LOD). This polymer, modified with a tertiary amine as a co-reactive group, exhibits aggregation-induced electrochemiluminescence (AIECL) and self-enhanced ECL behaviors. It is noteworthy that the tertiary amine also acts as I2vapor capturing and sensing groups to give a LOD of 0.13 ppt. Excellent selectivity was obtained in various interfering atmospheres. A new mechanism was discovered for designing vapor sensors, which is summarized as co-reactive group poisoning (CGP). To meet the high efficiency requirement of nuclear emergency monitoring, an I2sensor modified screen printed carbon electrode was used due to its low cost, lack of need for pretreatment and suitability for mass production. A matching upwardly photosensitive ECL dark box was further designed. This study reports ECL vapor monitoring for the first time and provides a novel strategy for early warning of a nuclear emergency, suggesting its significance in environmental and public security fields.

Synthesis and properties of dicarbazolyltriphenylethylene-substituted fluorene derivatives exhibiting aggregation-induced emission enhancement

Two novel dicarbazolyltriphenylethylene-substituted fluorene derivatives DctF and Dct2F were synthesized by the Wittig-Horner and Suzuki coupling reactions. It was reasoned that introducing linear alkyl chains into the fluorene structure could facilitate the deposition of high-quality films by an economical and simple process. The thin solid films of DctF and Dct2F show strongly enhanced emissions in comparison to their dilute solutions, which indicate the aggregation-induced emission enhancement (AIEE). Their decomposition temperatures (Td) exceed 400°C and the glass transition temperature (Tg) of DctF is 105°C. The maximum fluorescence emission wavelengths are in the region of 458-469 nm.
