In this study,two hydrogen-bonded organic frameworks(HOFs),namely,HOFTPE3N and HOFTPE4N,have been constructed from nitro-substituted tetraphenylethene.In HOFTPE4N,two types of pores are observed with
利用正己烷作为分散剂，用溶胶-凝胶法制备了粒径为2～3nm 超小氧化锌量子点，强烈的尺寸效应将紫外发光峰蓝移至深紫外区(300nm～360nm)，计算得其禁带宽度约为3.5～4.0eV.用巯基乙酸对获得的氧化锌量子点进行了修饰，并对影响修饰效果的因素(溶液浓度，溶液温度，溶液混合时间，氧化锌量子点与巯基乙酸的摩尔比)进行了研究.结果 表明，巯基乙酸修饰氧化锌量子点后可得到了来自氧化锌量子点带-带跃
基于共轭聚合物给体(D)/富勒烯受体(A)的聚合物太阳能电池,由于其低成本、柔性等特点,依然是光伏产业的重要方向.目前,其核心问题是光电转换效率仍达不到产业化的要求.多年来,基于激子理论的指导,尽管聚合物太阳能电池的光电转换效率已突破10％,但是,一方面基于该理论指导下的聚合物太阳能电池器件效率的提升已越发困难,另一方面,超快电荷分离现象的发现也对该理论提出了挑战.2012 年,Kaake 等人通
N-type semiconductor indium tin oxide(ITO)nanoparticles are used to effectively suppress the fluorescence blinking of single near-infrared-emitting CdSeTe/ZnS core/shell quantum dots(QDs),where the IT
A small-molecular acceptor,tetraphenylpyrazine-perylenediimide tetramer(TPPz-PDI4),which has a reduced extent of intramolecular twisting compared to two other small-molecular acceptors is designed.Ben
Although bright organic mechanoluminescence(ML)has been observed for a few luminophores with aggregation-induced emission(AIE),a feasible design principle for the AIE-ML compounds has not yet been pre
Recently,by selecting of the high-performance polymer PBDB-T as the electron donor1 and ITIC2 as the small molecule acceptor(SMA),the power conversion efficiencies(PCEs)in non-fullerene polymer solar
Two porphyrin small molecules substituted with either a furan-or a selenophenelinked diketopyrrolopyrrole unit have been designed and synthesized as an electron donor material for bulk heterojunction(
Organic-inorganic lead halide perovskites have attracted much attention because of their unique merits,such as excellent optical absorption,long-balanced carrier diffusion length and low-cost processi
