There are extensive reports on bathochromic emissive material associated with non-covalent interaction but the reports on emissive material with covalent crosslinked approach is limited. Therefore, we highlight unique method for synthesis of crosslinked polymeric materials formed via thermal Click reaction where the static aggregate of naphthalene (Np) in Polym-Np or pyrene (Py) in Polym-Py showed energy tunable emission. Initially, the crosslinked polymeric materials were well-characterized using spectroscopic and analytical methods like NMR, ATR-FTIR, rheometer, TGA and optical analysis. The energy tunability to fluorescence emission with polynuclear aromatic hydrocarbons (PAHs) - naphthalene and pyrene was observed. The quantum efficiency for the respective crosslinked polymers—Polym-Np and Polym-Py was found to be 2.54% and 8.72%. Moreover, the Full polarization fluorescence Mueller matrix (FLMM) spectroscopy was invoked to extract and quantify the molecular orientation of the ground and excited state of the crosslinked polymers—Polym-Np and Polym-Py. The polarization parameters (Fluorescence Diattenuation and Polarizance) based on fluorescence polarization showed that the PAHs within the crosslinked polymers found to be well organized in the excited state with respect to the ground state. Such materials have potential to application such as photocatalyst, chemosensor, etc.

使用光学参数分析光可调工程大分子荧光材料

关于与非共价相互作用相关的红移发光材料有大量报道，但关于共价交联方法的发光材料的报道是有限的。因此，我们重点介绍了通过热点击反应形成的交联聚合物材料的独特合成方法，其中 Polym-Np 中的萘 (Np) 或 Polym-Py 中的芘 (Py) 的静态聚集体显示出能量可调发射。最初，使用 NMR、ATR-FTIR、流变仪、TGA 和光学分析等光谱和分析方法对交联聚合物材料进行了很好的表征。观察到多环芳烃 (PAH) - 萘和芘对荧光发射的能量可调性。发现各自的交联聚合物——Polym-Np 和 Polym-Py 的量子效率为 2.54% 和 8.72%。而且，调用全偏振荧光穆勒矩阵 (FLMM) 光谱来提取和量化交联聚合物（Polym-Np 和 Polym-Py）的基态和激发态的分子取向。基于荧光偏振的偏振参数（荧光衰减和偏振）表明交联聚合物中的多环芳烃在激发态相对于基态组织良好。此类材料具有潜在的应用前景，如光催化剂、化学传感器等。基于荧光偏振的偏振参数（荧光衰减和偏振）表明交联聚合物中的多环芳烃在激发态相对于基态组织良好。此类材料具有潜在的应用前景，如光催化剂、化学传感器等。基于荧光偏振的偏振参数（荧光衰减和偏振）表明交联聚合物中的多环芳烃在激发态相对于基态组织良好。此类材料具有潜在的应用前景，如光催化剂、化学传感器等。
