Z-shape (1,2,7,8-tetrasubstituted) perylene derivatives are novel chromophores with great potential in various applications. Yet, the synthetic entry into this class of molecules is hitherto quite limited. In this communication, the synthesis of a series of Z-shape perylene derivatives via a double Wittig–Knoevenagel benzannulation protocol is reported. Preliminary photophysical and electrochemical
Z形(1,2,7,8-四取代)per衍生物是新型发色团,在各种应用中均具有巨大潜力。然而,迄今为止,合成合成进入这类分子的方法非常有限。在这种交流中,报道了通过双重Wittig–Knoevenagel苯并环协议合成一系列Z形per衍生物。初步的光物理和电化学研究表明,这些新的per系统的前沿轨道能级受电子,区域化学和构象效应的调节。
