A cover I designed for the Cooper Group’s work on COF catalysis has been published in Nature Chemistry (article link, screengrab).
This was one of several variations on the design (click for high-res):
Although organic photocatalysts are an attractive option for water splitting because they can be tuned relatively easily through synthesis, they tend not to be very efficient. Now, a team led by Andrew Cooper has shown that a covalent organic framework (COF) comprising β-ketoenamine nodes and benzothiophene sulfone-based linkers is a good hydrogen-evolution catalyst (an artistic representation of the process is shown on the cover). Its activity — attributed to the COF’s crystallinity, strong visible-light absorption and the wettable, hydrophilic nature of its sulfone-lined mesopores — can be further improved by dye sensitization.
