【摘要】 太阳能是取之不尽、用之不竭的清洁能源。设计合成具有光电或光化学能转化的半导体材料是实现太阳能转换和存储等重要应用的关键。杂化半导体材料由于兼具无机/有机组元优点、结构多样性,以及性能易调控等特点,近年来受到广泛关注。但是,目前所报道的大部分杂化半导体材料往往只有一种成分具有半导体性;例如常见的钙钛矿碘化铅甲胺只有无机的碘化铅是半导体性的,而有机甲胺为普通的抗衡离子。假如杂化半导体材料的无机和有机的组分均具有半导体性能,那么该杂化半导体材料将会是一种分子水平上的异质结,将更加有利于光致电荷分离。这里将向大家简要地介绍我们课题组近两年利用超分子工程策略设计合成得到的一些具有独特的光电性能的双半导体组元杂化材料(图1)[1]。更多还原

【Abstract】 Semiconductive hybrid materials are a fascinating class of functional materials since their enormous potential applications.Generally,such semiconductive materials are reported to be constructed from one semiconductive inorganic(or organic) component with another common component.Recently,more and more attention has been drawn to those whose both organic and inorganic components are semiconductive.It is conceivable that the combination of semiconductive inorganic and organic components in one material is anticipated to form a unique heterostructure with synergetic properties of two components.In this report,I will give our recent results on 1D,2D and 3D hybrid materials composed of semiconductive inorganic polyoxometalates or metal halides with organic naphthalene diimides or bipyridinium derivatives through supramolecular interactions(coordination,H-bonding and anion-π interactions et al).Their photophysical properties,particularly photo-induced electron-transfer properties have also been discussed.更多还原
