Electrically conductive hybrid organic crystals as flexible optical waveguides حسب Li, Liang

"…The elements respond rapidly to temperature by curling or uncurling in about 0.2 s, which in one typical case corresponds to exceedingly fast deformation and recovery rates of 2187.5° and 1458.3° , respectively. In cyclic operation mode, their conductivity decreases less than 1% after 10,000 thermal cycles. …"
