Synthesis and structures, photo function of imide-based oligomers which make an integrated form regulatable.

在这项研究中，我们计划合成具有芳香族二酰亚胺单元的环状和链状齐聚物，并通过控制它们的集成形式来开发它们的光功能。~1H核磁共振氢谱和吸收光谱表明，由萘二亚胺和二甲苯单元构成的[3+3]环状低聚物由于电荷转移相互作用而发生自缔合。以双亚胺为核心单元的给体-受体链状低聚物，由于其扭曲的结构，出人意料地表现出一些特殊的光性能。此外，在这些低聚物中还观察到了从给体单元到受体单元的光诱导的分子间或分子内电子转移。

In this study, we planned to synthesize the cyclic and chain oligomers with aromatic diimide units, and to develop their photo function by controlling their integrated form. The [3+3] cyclic oligomer constructed with naphthalene diimide and xylylene units was revealed a self-association due to a charge-transfer interaction by ^1H NMR and absorption spectra. The donor-acceptor chain oligomers with the perylene bisimide core unit exhibit some specific photoproperties unexpectedly from their twisted structure of perylene unit. Furthermore, photoinducedinter- or intramolecular electron transfer from donor unit to acceptor unit was observed in these oligomers.
