In this work we demonstrate, for the first time, the use of polylactic acid (PLA) as a biodegradable host matrix for the construction of the active emissive layer of organic light‐emitting diode (OLED) devices for potential use in bioelectronics. In this preliminary study, we report a robust synthesis of two fluorescent PLA derivatives, pyrene‐PLA (AH10) and perylene‐PLA (AH11). These materials were prepared by the ring opening polymerisation of l‐lactide with hydroxyalkyl‐pyrene and hydroxyalkyl‐perylene derivatives using 1,8‐diazabicyclo[5.4.0]undec‐7‐ene as catalyst. OLEDs were fabricated from these materials using a simple device architecture involving a solution‐processed single‐emitting layer in the configuration ITO/PEDOT:PSS/PVK:OXD‐7 (35%):AH10 or AH11 (20%)/TPBi/LiF/Al (ITO, indium tin oxide; PEDOT:PSS, poly(3,4‐ethylenedioxythiophene) doped with poly(styrenesulfonic acid); PVK, poly(vinylcarbazole); OXD‐7, (1,3‐phenylene)‐bis‐[5‐(4‐tert‐butylphenyl)‐1,3,4‐oxadiazole]; TPBi, 2,2′,2″‐(1,3,5‐benzenetriyl)tris(1‐phenyl‐1H‐benzimidazole)). The turn‐on voltage for the perylene OLED at 10 cd m–2 was around 6 V with a maximum brightness of 1200 cd m–2 at 13 V. The corresponding external quantum efficiency and device current efficiency were 1.5% and 2.8 cd A–1 respectively. In summary, this study provides proof of principle that OLEDs can be constructed from PLA, a readily available and renewable bio‐source. © 2020 The Authors.

聚乳酸-per衍生物用于蓝色可生物降解的有机发光二极管
在这项工作中,我们首次证明了聚乳酸(PLA)作为可生物降解的基质的用途,用于构建有机发光二极管(OLED)器件的有源发射层,可用于生物电子领域。在此初步研究中,我们两个荧光PLA衍生物,芘-PLA(的稳健性AH10)和苝-PLA(AH11)。这些材料是通过使用1,8-二氮杂双环[5.4.0]十一碳-7-烯作为催化剂,使l-丙交酯与羟烷基‐和羟烷基per衍生物进行开环聚合而制备的。OLED是使用简单的设备体系结构由这些材料制成的,该体系结构包括配置为ITO / PEDOT:PSS / PVK:OXD-7(35%)的溶液处理的单发射层:AH10或AH11(20%)/ TPBi / LiF / Al(ITO,铟锡氧化物; PEDOT:PSS,掺杂有聚(苯乙烯磺酸)的聚(3,4-乙二氧基噻吩); PVK,聚(乙烯基咔唑); OXD-7 ,(1,3-亚苯基)-双[5-(4-叔丁基苯基)-1,3,4-恶二唑]; TPBi,2,2',2″-(1,3,5-苯三基) tris(1-苯基-1H-苯并咪唑))。ylene OLED的启动电压在10 cd m –2时约为6 V,在13 V时最大亮度为1200 cd m –2。相应的外部量子效率和器件电流效率分别为1.5%和2.8 cd A – 1个。总而言之,这项研究提供了可以从PLA(一种容易获得的可再生生物资源)构建OLED的原理证明。©2020作者。聚合物国际 由John Wiley&Sons Ltd代表工业化学协会出版。
