The effect of complexation with platinum in polyfluorene derivatives: A photo- and electro-luminescence study

Two‐photon excitation and optical limiting in polyfluorene derivatives

“…Using distinct synthesis routes, other chemical pendants can be attached with the polymer backbone of these polyfluorene derivatives, which could increase even more its 2PA cross‐section values. The polymers presented a strong two‐photon luminescence and also displayed optical limiting behavior, which, in combination with their properties previously reported in the literature,1, 10, 31 such as film‐forming ability, chemical stability, and electroluminescence, make them highly promising for designing optical and photonic devices.…”

“…The synthesis routes of LaPPS 16, LaPPS 29, and LaPPS 42, whose chemical structures are displayed in Figure 1(a–c), respectively, are fully described in previous studies,1, 10, 30, 31 but a few details will be given here. LaPPS 16 and LsPPS 29 were synthesized following the Wittig reaction 32.…”

“…Fluorene‐based pi‐conjugated polymers have emerged as suitable emitting materials for a variety of applications due to the combination of versatile chemical structure1, 2 with highly efficient photoluminescence and electroluminescence,3, 4 thermal and oxidative stability, good film‐forming, and hole‐transporting properties 5, 6. Furthermore, the polarized emission7 and high charge carrier mobility prompted their use in nanowire waveguides and transistors,8, 9 as well as in electroluminescent and photovoltaic devices.…”

Photo- and electroluminescence in a series of PPV type terpolymers containing fluorene, thiophene and phenylene units

“…The correlations between light emission processes with chemical structure and morphology is of prime importance for the comprehension of the operating phenomena in the various optoelectronic devices and related applications of electronic polymers [1,2]. The chemical linking of monomers in copolymerization or the mixing of polymers in blend fabrication [3] are powerful tools to tune light emission and output yield in LEDs [4,5] and photovoltaic efficiency in solar cells [6,7] apart from other applications.…”

ATRP Initiators Based on Proton Transfer Benzazole Dyes: Solid-State Photoactive Polymer with Very Large Stokes Shift

“…Fluorescent polymer matrices have been shown to be of great importance for the emergence of new technologies in several areas, such as in optical data storage devices, fluorescent probes for ions and organic molecules, solid-state laser devices, and biological imaging . Polymer-based matrices that are not intrinsically luminescent can become photoactive based on emissive moieties covalently linked or not to the polymer backbone, including metal complexes, rare earth metals, or organic dyes of various classes. , In this regard, organic dyes are considered the best alternative for such applications, as their absorption range is wide and their synthetic costs are not prohibitive. In addition, it is possible to modulate the structure conjugation or even to add new chromophoric or auxochromic groups by magnifying the electron donor or acceptor effects, tuning its photophysical properties. − …”
