DOI: 10.1002/cssc.202300019
Abstract: Incorporating photo-switches into pores of microporous materials yield photo-responsive materials for low-energy CO2capture. However, such approaches reduce CO2 uptake of these materials. Here we overcome this limitation by exploiting trans-cis photoisomerization of azobenzene located in the pores of a hypercrosslinked… read more here.
