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

在本研究中，我们计划合成含有芳香二酰亚胺单元的环状和链状低聚物，并通过控制其整合形式来开发其光功能。由萘二酰亚胺和苯二甲基单元构成的[3+3]环状低聚物通过^1H NMR和吸收光谱证实了由于电荷转移相互作用而产生的自缔合。以苝酰亚胺为核心单元的给受体链齐聚物由于其苝单元的扭曲结构而表现出一些出乎意料的特殊光性能。此外，在这些寡聚体中观察到了光诱导的从供体单元到受体单元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.
