WebA higher M n often improves device performance. 61 In that respect, we note that the two polymers with chlorinated side chains (J71–Cl and J101) have somewhat lower M n than the other two (J71 and J100) but still give rise to higher PCEs. This supports our conclusion that chlorination of the side chains causes the beneficial effect. WebSide chain chlorinations of aromatic compounds are usually carried out above 80° C. This is because lower temperatures are conducive to nuclear chlorination and it is more difficult to sustain free radical chain reactions at lower temperatures. However, when the resulting chlorinated products are thermally unstable, a problem results.
