  We present a new class of solubilizing groups for conjugated polymers that enable solution processing of multilayer devices. Conjugated polymers in organic devices are sometimes difficult to process, because of their limited solubility. Well-soluble polymers decorated with alkyl side chains, however, introduce new challenges for thin-film deposition. Using the same solvent for multiple layers can dissolve the already applied layers. In this work, we introduce a new class of thermo-labile groups, which reduce the solubility of conjugated polymers after thermal treatment. Following a very modular approach, we can tune the temperature of the thermo-cleavage between 140 °C and 200 °C. This enables the fabrication of organic solar cells and field-effect transistors (FETs) with robust, solvent-resistant active layers.

  我们提出了一类新的共轭聚合物增溶基团，可用于多层器件的溶液加工。有机器件中的共轭聚合物有时很难加工，因为它们的溶解度有限。然而，用烷基侧链装饰的易溶聚合物为薄膜沉积带来了新的挑战。使用相同的溶剂进行多层沉积可能会溶解已沉积的层。在这项工作中，我们引入了一类新的热敏基团，它们能在热处理后降低共轭聚合物的溶解度。通过模块化方法，我们可以在 140 °C 至 200 °C 之间调节热裂解温度。这样就能制造出具有坚固耐溶剂活性层的有机太阳能电池和场效应晶体管（FET）。

• Electronic properties of the nitrone substituent. Stabilization of benzylic carbocations
  作者：Xavier Creary、Kresna Hartandi

  The nitrone substituent CH=N(O) t-Bu is electron-withdrawing with a Taft sigma (1) value of 0.20. It also retards the solvolysis rate of a cumyl chloride when placed in the meta-position (sigma (+) = 0.20). However, CH=N(O) t-Bu becomes weakly cation stabilizing when placed in the para-position of a cumyl cation (sigma (+) = -0.04). This weak cation stabilization is a result of a conjugative interaction which delocalizes charge and offsets the inductive effect of the nitrone. When the nitrone is placed in the para-position, but then twisted out of conjugation with the aromatic ring by incorporation of flanking 3,5-dimethyl groups, it again retards solvolysis rates. Computational studies (B3LYP/6-31G*) show that the nitrone substituent stabilizes a para-substituted benzyl cation relative to the meta-substituted analog by a conjugative interaction. However, the calculated stabilization greatly overestimates the cation stabilization seen in solvolytic reactions. Copyright (C) 2001 John Wiley & Sons, Ltd.
