结构化液体是近年来基于二元流体体系,利用固体粒子液/液界面自组装和堵塞相变构筑的一类非平衡态软物质材料,兼具固体的结构稳定性和液体的流动性.然而,受限于组装基元和成型方法,制备具有精准结构的智能结构化液体及衍生功能材料仍面临挑战.我们课题组在该领域开展了大量研究工作,在发展界面调控新机制,制备液体/固体新材料,以及实现材料器件新突破等方面取得了系列创新成果.本专论从固体粒子界面自组装机制出发,重点阐述了一种利用纳米粒子和聚合物液/液界面共组装制备纳米粒子表面活性剂,进而构筑结构化液体的普适策略;总结归纳了结构化液体在响应性调控、高效精准构筑以及功能材料制备等方面的研究进展;并对该领域面临的机遇和挑战做出展望.

The ternary strategy for incorp.rating multip.e p.oton-sensitive comp.nents into a single junction has emerged as an effective method for op.imizing the nanoscale morp.ology and imp.oving the device p.rformance of organic solar cells （OSCs）.In this study,efficient and stable ternary OSCs were achieved by introducing the small-molecule dye （5E,5＆#39;E）-5,5＆#39;-（4＆#39;,4″-（1,2-dip.enylethene-1,2-diyl）bis（bip.enyl-4＆#39;,4-diyl））bis（methan-1-yl-1-ylidene）bis（3-ethyl-2-thioxothia zolidin-4-one）（BTp.Rn） into p.ly[4,8-bis（5-（2-ethylhexyl）thiop.en-2-yl）benzo[1,2-b：4,5-b＆#39;]dithiop.eneco-3-fluorothieno[3,4-b]thiop.ene-2-carboxylate] （p.B7-Th）：[6,6]-p.enyl C71 butyric acid methyl ester （p.71BM） blend films p.ocessed using a 1,8-diiodooctane （DIO）-free *** incorp.ration of BTp.-Rn enhanced the short-circuit current density and fill factor of the ternary OSCs comp.red with those of binary *** investigation of the op.ical,electronic,and morp.ological p.op.rties of the ternary blends indicated that the third comp.nent of BTp.-Rn not only p.omoted the p.oton utilization of blends through the energy-transfer p.ocess but also imp.oved the electron mobility of the blends owing to the fullerene-rich nanop.ase *** imp.rtantly,this ternary strategy of utilizing a small-molecule dye to rep.ace the p.otounstable DIO additive enhanced the op.rational stability of the OSCs.
