Description

2,2'-(4-Bromo-1-Butenylidene)Bis-3-Methyl-D6-Thiophene is a deuterated, brominated conjugated small molecule engineered for high-performance optoelectronic applications. Its fully deuterated thiophene rings and defined alkene-bridged bis-heteroaromatic structure confer enhanced thermal stability, reduced vibrational quenching, and superior photophysical properties critical for next-generation organic semiconductors. This compound is essential for R&D and pilot-scale manufacturing in organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and field-effect transistors (OFETs), particularly where isotopic labeling enables precise mechanistic studies or performance optimization.

Application

• Active layer component in high-efficiency solution-processed organic photovoltaic (OPV) cells
• Electron-donor material in bulk heterojunction (BHJ) solar cell architectures
• Deuterated building block for synthesizing stable, low-voltage OLED emitters and host materials
• Model compound in ultrafast spectroscopy studies of exciton dynamics in π-conjugated systems
• Key intermediate in the preparation of D6-labeled polythiophene derivatives for neutron scattering analysis
• Charge-transport layer additive to improve mobility and reduce trap-assisted recombination in OFETs
• Reference standard for quantitative mass spectrometry (MS) and NMR method development in deuterium incorporation studies
