The cross-coupling reaction of organic electrophiles with organostannanes, traditionally known as the Stille reaction, has found renewed interest in the preparation of new organic materials such as conjugated polymers, organic semiconductors and photoactive molecules for use in organic photovoltaics. Moreover, a very recent field in which the Stille reaction has found successful application is that of the design and synthesis of new photosensitizers for dye-sensitized solar cells (DSSCs). DSSCs are considered a promising alternative for energy production from renewable sources. In such devices light harvesting is carried out by a dye which is generally a highly conjugated molecule. Due to the mild operating conditions and the high functional-group compatibility, the Stille reaction proved to be a powerful tool not only for the preparation of photosensitizers, but also to plan their chemical elaboration in order to tune and optimize their photophysical, electrochemical and photovoltaic properties. In this microreview some recent examples of the Stille reaction in the synthesis of organic dyes for DSSC are reported.
有机亲电试剂与有机锡烷的交叉偶联反应，传统上称为施蒂勒反应，在制备新型有机材料（如用于有机光伏的共轭聚合物、有机半导体和光活性分子）方面重新引起了人们的兴趣。此外，施蒂勒反应最近成功应用的一个领域是设计和合成用于染料敏化太阳能电池（DSSC）的新型光敏剂。DSSC被认为是一种利用可再生能源生产能源的有前途的替代方案。在这类器件中，光捕获是由一种染料进行的，这种染料通常是一种高度共轭的分子。由于温和的操作条件和高官能团兼容性，施蒂勒反应不仅被证明是制备光敏剂的有力工具，而且还可用于规划其化学修饰，以调节和优化其光物理、电化学和光伏性能。在这篇微型综述中，报道了施蒂勒反应在合成用于DSSC的有机染料方面的一些最新实例。
