Abstract
This work presents the synthesis of a new polysilane-carbazole structure (PSCB) by hydrosilylation in solvent-free conditions. For this purpose a polyhydrosilane (PSH) with a high content in methylhydrosilyl groups was mixed with 2-(((2-(9H-carbazol-9-yl)ethoxy)carbonyl)amino)ethyl methacrylate (CB) and triturated in the presence of Karstedt catalyst. The reaction proceeds smoothly in normal conditions of pressure and temperature in a dry atmosphere. The chemical structure of the resulted polymer was determined using Fourier-transform infrared (FTIR) and proton nuclear magnetic resonance (1H NMR) spectroscopies. Gel permeation chromatography (GPC) analysis proved the completion of the addition reaction in high yields. The computational analysis reveals the electronic structures of both CB and the PSCB molecule and highlights the significance of conformational effects on electronic structure and emission properties. The carbazole moiety acts as an electron donor, while the polysilane chain serves as an acceptor, enabling an intra-molecular through bridge charge transfer. Fluorescence measurements validate the unique structure, demonstrating an amplified emission due to the cumulative effect of the polysilane chain. The polysilane-carbazole polymer holds promise for various applications, emphasizing its potential in optoelectronic devices and sensing technologies.
