Next-Generation Organic Semiconductor Laser Materials
POSTED BY 14 May, 2026
We are excited to share our latest work on tuning oligophenylenes for highly efficient organic lasing, now published in J. Am. Chem. Soc.
By integrating rigid and planar molecular architectures, we achieved ultrafast excited state dynamics with exceptionally fast radiative decay rates (>2 × 109 s-1), ultrahigh emission cross-sections (up to 1.01 × 10−15 cm2) and short fluorescence lifetimes (<0.5 ns). These characteristics enabled excellent solid-state amplified spontaneous emission (ASE) thresholds (0.67−0.80 μJ cm−2).
These state-of-the-art photophysical and lasing properties further expand the performance limits of organic laser materials and provide new molecular design for next-generation organic photonics technologies.
