Star-shaped ladder-type ter(p-phenylene)s for efficient multiphoton absorption

Star-shaped ladder-type ter(p-phenylene)s exhibit remarkably efficient multiphoton absorption properties with 2PA cross-section up to 2579 GM at 700 nm and 3PA cross-section up to 3.35 x 10(-76) cm(6) s(2) in the femtosecond regime for a blue-emissive molecule despite having such a short pi-conjugated framework.
