Polymers which have numerous conjugated double bonds can be used as PLED materials, such as the polyethersulfone (PES) and its derivatives. Therefore, further research on the synthesis of PES and its derivatives is needed to explore their potential as PLED materials. In this research, the synthesis of polyethersulfone has been performed utilizing Microwave Assisted Organic Synthesis (MAOS) method and subsequently the synthesized PES was being transformed into the nitrated PES (PES-NO2) and the aminated PES (PES-NH2) utilizing the conventional method (reflux). The structure of the synthesized polymers was confirmed by analyzing the FT-IR and 1H-NMR spectra data. The potent of the synthesized polymers as PLED material was analyzed from fluorescence emission spectral data (in NMP, N-methyl pyrrolidone) showing the maximum emission wavelengths in the blue light of visible area, which were 444 nm (PES); 356 nm and 444 nm (PES-NO2); and 440 nm (PES-NH2). These results showed that all of the synthesized polymers have the potent to be used as PLED.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Conjugated double bonds,Conventional methods,Fluorescence emission,MAOS,N-methylpyrrolidone,PLED,Polymer light-emitting diodes,Synthesized polymers[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Fluorescence,MAOS,PES,PES-NH2,PES-NO2,PLED[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research was partially funded by Riset Desentralisasi Dikti 2016 granted to the corresponding author (2b*).
