Metal-organic frameworks with desirable properties can be designed through careful choice of linker and node combinations, but achieving the synthesis of a desired MOF is complex and dependent on many experimental variables. Here, a genetic algorithm combined with experimental feedback and confirmation is used to obtain the optimal microwave-assisted synthesis conditions for a porphyrin-based aluminium MOF (Al-PMOF), achieving excellent crystallinity and a close to 80% yield in only the 2^nd generation.

Automated systems, nowadays more commonly used in laboratory settings, are typically fixed to a narrow set of reactions and used within a complex laboratory environment. Now, a portable platform has been developed for the on-demand and on-site multistep synthesis of organic molecules, oligonucleotides and oligopeptides mapped into reactionware systems.

A forward-synthesis platform, Allchemy, computationally determines how to ‘close the circle’, or use waste chemicals to make valuable pharmaceutical or agrochemical products, ranking possible routes by environmental, geospatial, and other factors.

Development of organic electronic materials relies on understanding structure-function relationships in conjugated polymers but the synthetic workload to make large numbers of new compounds presents a practical barrier to properly survey conjugated organic derivatives. Here, the authors use automated synthesis to prepare a library of conjugated oligomers with systematically varied side chain composition followed by single-molecule characterization of charge transport.

PMOs (phosphorodiamidate morpholino oligomers) have huge potential for antisense therapy but complex and slow synthesis limits application. Here, the authors report the development of automated flow synthesis methods which reduce nucleobase coupling times from hours to minutes removing human errors and allow for high-throughput production.
