DOI: 10.1021/acs.macromol.7b01722
Abstract: Two helical conjugated ladder polymers (CLPs) have been synthesized using the photochemical cyclo-dehydrochlorination (CDHC) reaction on polychlorinated polymer derivatives. UV–vis and photoluminescence spectroscopy revealed that the outer chlorinated rings (phenyl or thiophene) used for the… read more here.

Abstract: We report a nontraditional synthesis of cyclopentafused-polycyclic aromatic hydrocarbon embedded ladder polymers using a palladium catalyzed cyclopentannulation polymerization followed by a cyclodehydrogenation reaction. Donor-acceptor type polymers containing a cyclopenta[hi]aceanthrylene acceptor groups can be synthesized by… read more here.

DOI: 10.1126/science.abl7163
Abstract: Membranes have the potential to substantially reduce energy consumption of industrial chemical separations, but their implementation has been limited owing to a performance upper bound—the trade-off between permeability and selectivity. Although recent developments of highly… read more here.
