功能化的、发光的、基于芘的单体的开发已经并且继续是在光学和电子器件的设计和制造方面非常感兴趣的领域。在此，一个简单的策略，以调整芘为基础的发色团的发光颜色已经建立了通过简单的官能团修饰的对位上的二苯氨基的供体积木。在不同的解决方案，并在固态中获得和描述了有趣的物理性质。所得结果可以用Hammett方法和密度泛函理论（DFT）计算来解释。苯基官能团的Hammett σ参数与发射光谱的波数（cm ~（-1））有很好的相关性。这种正相关性，即官能团的σ常数与单体的发射性质之间的正相关性，可以用于开发这些类型的系统的预测方法。
The development of functionalized, luminescent, pyrene-based monomers has been and continues to be an area of great interest in terms of the design and fabrication of optical and electronic devices. Herein, a facile strategy to tune the emission color of pyrene-based chromophores has been established by simple functional group modification at theparaposition to the diphenylamino on the donor building block. Intriguing photophysical properties were obtained and are described both in different solutions and in the solid state. The results obtained could be explained by the Hammett method and by density functional theory (DFT) calculations. A good correlation was observed between the Hammett σparaconstants of the functional groupsparato the phenyl and the wavenumber (cm–1) of the emission profile. This positive correlation, namely between the σ constants of the functional groups and the emission properties of the monomers, can be used to develop a predictive method for these types of systems.
