The next saga of depolymerization is finally here: doing something with it! @KadenStevens12 new paper in @ACSCentSci uses depzn to etch polymerization-induced microphase separations (PIMS), giving mesoporous monoliths that uptake dye after PPM sulfonation! https://t.co/kpn5Whsd0T

Thermally triggered depolymerization has traditionally been viewed through the lens of sustainability and recycling, not as a constructive tool for materials design. Herein, we show that selective,...
