“…A relatively high thin film photoluminescence quantum yield of 22% was observed in marked contrast to other reported anthracene conjugated polymers which exhibit severe PL quenching in the solid state. 32,45 We fabricated OLED devices by incorporating the copolymers in LEDs with ITO/PEDOT:PSS (50 nm) anode and thermally evaporated Ca (30 nm)/Al (150 nm). 20 We deposited the active layer (90 nm) via spin coating from a 10 mg mL −1 chlorobenzene solution.…”

We present the synthesis of a novel diphenylanthracene (DPA) based semiconducting polymer. The polymer is solubilised by alkoxy groups attached directly to a DPA monomer, meaning the choice of co-monomer is not limited to exclusively highly solubilising moieties. Interestingly, the polymer shows a red-shifted elecroluminescence maximum (510 nm) when compared to its photoluminescence maximum (450 nm) which we attribute to excimer formation. The novel polymer was utilised as a host for a covalently-linked platinum (II) complexed porphyrin dopant. Emission from these polymers was observed in the NIR and again showed almost a 100 nm red shift from photoluminescence to electroluminescence. This work demonstrates that utlising highly aggregating host materials is an effective tool for inducing red-shifted emission in OLEDs

Abstract. Miyaura-Suzuki type polycondensation with no use of n-BuLi for preparation of precursors was carried out to obtain a series of -conjugated materials having multi-functionality. Bully substituent in the monomer restricts propagation in the polycondensation to give high molecular weight products. Although the products thus obtained show low molecular weight, the resultant materials show good optical absorption and fluorescence.

“…Anthracene derivatives with extended side groups can also be engineered to emit in the green instead of the usual violet-blue range. [24] However, outside the more common range of the PFO derivatives, only a few specifically constructed 𝜋-conjugated copolymers have been demonstrated to show green fluorescence (Table 1). [25,26,27] Thus, we believe there is a need for high-efficiency green-emitting CPs with relatively facile synthesis.…”

This work synthesizes a green‐fluorescent conjugated polymer and performs basic photophysical characterization of this new material. Atums Green[1] is synthesized by a Suzuki cross‐coupling polymerization reaction between isostructural dibromo and diboronic acid monomers and is structurally characterized by nuclear magnetic resonance and gel permeation chromatography. The polymer consists of an alkoxy‐substituted 1,4‐bis((E)‐styryl)benzene repeating unit with molecular weight up to Mn = 50 kDa relative to polystyrene. Atums Green shows a strong green fluorescence maximized at ≈500 nm in chloroform and tetrahydrofuran solutions, with an absolute quantum efficiency as high as 98%. The photobleaching dynamics and time‐resolved photoluminescence (TRPL) are measured both in solutions and in solid films. Finally, solution‐based lasing is demonstrated in a bulk lasing cavity and in a cylindrical microcavity. Lasing emission is readily achieved in both formats, indicating that Atums Green has excellent emission characteristics, and further suggesting that it may present a viable green‐emitting conjugated polymer materials system for light emission applications.
