Triphenyl-(4-triphenylsilylphenyl)silane (CAT: M440031) is a silane-based organic semiconductor designed as a high-triplet-energy host and structural material for optoelectronic applications. Its rigid, bulky triphenylsilyl substituents provide excellent morphological stability, efficient suppression of aggregation, and strong film-forming ability. With high thermal durability and wide bandgap characteristics, TSPS is particularly effective as a host material in organic light-emitting diodes (OLEDs), especially for blue phosphorescent and thermally activated delayed fluorescence (TADF) emitters. By ensuring balanced charge transport and exciton confinement, TSPS contributes to enhanced device efficiency and lifetime. Its robust structure makes it a versatile material for next-generation OLED displays and lighting technologies.
