Abstract
The generation of a low HOMO-LUMO energy gap makes organic polymer-based composites an important class of materials with outstanding catalytic efficiency. The present work describes the simple and direct synthesis of an excellent photocatalyst, PC (C26H16NO7S)n via doping of erythrosine-B dye on sulfone infused poly(2-amino thiophenol) assembly (PA, (C6H4NO2S)n). The O 1 s spectrum displays peaks at 531.8 eV and 533.3 eV, representing the O=C and O–C groups of the in-situ generated fluorescein loaded on PA surface. Through absorption study (Tauc’s plot), the optical band gap (Eg) for polymer PA (2.9 eV) and photocatalyst PC (2.1 eV) has been calculated. Further, due to the efficient absorbance in the range of 400–600 nm with a low optical band gap, the applicability of the catalyst, PC has been checked in photocatalytic C–H activation in thiophene, and the generation of C–C bond with p-nitro aryldiazonium salt.
低 HOMO-LUMO 能隙的产生使有机聚合物基复合材料成为一类具有出色催化效率的重要材料。本研究介绍了通过在注入砜的聚（2-氨基噻吩酚）组件（PA，(C6H4NO2S)n）上掺杂赤藓红-B 染料，简单直接地合成了一种优异的光催化剂 PC (C26H16NO7S)n。O 1 s 光谱在 531.8 eV 和 533.3 eV 处出现峰值，代表原位生成的荧光素负载在 PA 表面的 O=C 和 O-C 基团。通过吸收研究（陶氏图），计算出了聚合物 PA（2.9 eV）和光催化剂 PC（2.1 eV）的光带隙（Eg）。此外，由于 PC 在 400-600 纳米范围内具有高效吸收率和较低的光带隙，催化剂 PC 在光催化噻吩中的 C-H 活化以及与对硝基芳基偶氮盐生成 C-C 键方面的适用性得到了验证。
期刊介绍：
Main Group Chemistry is intended to be a primary resource for all chemistry, engineering, biological, and materials researchers in both academia and in industry with an interest in the elements from the groups 1, 2, 12–18, lanthanides and actinides. The journal is committed to maintaining a high standard for its publications. This will be ensured by a rigorous peer-review process with most articles being reviewed by at least one editorial board member. Additionally, all manuscripts will be proofread and corrected by a dedicated copy editor located at the University of Kentucky.
