Ethylenes, thermochromic

The thermochromic ethylene 373 has been efficiently prepared in 96% yield by the microwave promoted condensation of anthrone with thioxanthone (Equation 83) <2003JCM260>. [Pg.849]

An opposite type of behavior, positive ionochromism, is shown by the polymer [C2H50CH2CH20(CH2)5]2Si n52- In this case, as shown in Figure 9, addition of lithium triflate to a thin film of the polymer promotes a bathochromic shift, increasing the midpoint temperature of the thermochromic transition from —45 to +50 °C Probably in this example the lithium ions, complexed to the ethylene oxide units, lock the polymer... [Pg.556]
