摘要
纯有机室温磷光(RTP)材料因其潜在的应用价值而备受关注.迄今,多数已报道的有机RTP材料在晶态下发射出较强的RTP,但在溶液加工过程中易生成无定形态,从而失去RTP性能.本文通过一锅法两步反应,合成了含有多个甲氧基的二氟化硼衍生物(BF2-tPMO).晶体结构分析表明,多个甲氧基的存在构建了有效的分子间非共价相互作用.这些非共价键作用可抑制分子运动,保持较高的发光效率.此外,这些非共价键作用能够使其在溶剂处理后依然保持晶态性质,进而保持RTP性能.实验结果表明,BF2-tPMO可溶解在不同溶剂中且在溶剂蒸发后仍能保持相同的RTP特性,为易加工型RTP材料的设计提供了有效的策略.
Abstract
Pure organic room-temperature phosphorescent(RTP)materials have been under wide investigation due to their various potential applications.Till now,most reported organic RTP materials emit robust RTP in crystalline state,but lose RTP properties during the solution processing.Here,a boron-difluoride derivative bearing multiple methoxy group(BF2-tPMO)was synthesized through a one-pot two-step reaction.The existence of multiple methoxy groups helped to construct effective intermolecular non-covalent interactions,as revealed by X-ray single crystal structure.These intermolecular non-covalent interactions might help to alleviate molecular motions to increase emission efficiency,and also help to maintain its crystalline nature during the evaporation of organic solutions to keep its RTP character.Our experimental results indicate that BF2-tPMO maintained its RTP properties after solution processing,providing an effective strategy for designing RTP materials with convenient manipulation.
