资源简介：
Two-dimensional urea- and thiourea-containing covalent organic
frameworks (COFs) were synthesized at ambient conditions at large
scale within 1 h in the absence of an acid catalyst. The site-isolated
urea and thiourea in the COF showed enhanced catalytic efficiency
as a hydrogen-bond-donating organocatalyst compared to the molecular
counterparts in epoxide ring-opening reaction, aldehyde acetalization,
and Friedel–Crafts reaction. The COF catalysts also had excellent
recyclability.
