Abstract:The exploration of solid-state optical power limiting (OPL) materials based on nonlinear absorption (NLA) with heat resistance is essential and leading-edge. We present two types of poly(arylene ether sulfone)s (PAESs) derived from platinum acetylide, featuring varying conjugation lengths and platinum contents. The platinum-incorporated PAESs exhibit outstanding thermal properties (T g > 180 °C, T d5% ≥ 400 °C) with easy processing into solid films from solvents. Photophysics, ultrafast transient absorption, Z… Show more
