“…238 Photochemical reactions are a particular class of reactions in 100 which proximity between the reacting groups and stabilisation of a given conformation in the ground and excited states are important parameters which influence the reaction pathway. 239,240 Activity and selectivity are greatly affected by the reaction media: the solid state, [240][241][242][243][244][245][246] within a liquid crystal, 247 presence of a 105 stoichiometric [248][249][250][251][252][253][254][255][256][257][258][259] or a catalytic [260][261][262] amount of a hydrogen bond template, 263,264 zeolites, 265 dendrimers, micelles, and any other covalent or non-covalent hosts. 239,240 Cyclodextrin, [266][267][268][269][270][271][272][273][274][275][276][277][278] cucurbituril, 276,[279][280][2...…”

The design of artificial catalysts able to compete with the catalytic proficiency of enzymes is an intense subject of research. Non-covalent interactions are thought to be involved in several properties of enzymatic catalysis, notably (i) the confinement of the substrates and the active site within a catalytic pocket, (ii) the creation of a hydrophobic pocket in water, (iii) self-replication properties and (iv) allosteric properties. The origins of the enhanced rates and high catalytic selectivities associated with these properties are still a matter of debate. Stabilisation of the transition state and favourable conformations of the active site and the product(s) are probably part of the answer. We present here artificial catalysts and biomacromolecule hybrid catalysts which constitute good models towards the development of truly competitive artificial enzymes.

“…While the photochemical activation of molecules in solution is a well-known phenomenon, its integration with milling mechanochemistry has largely remained unexplored. The first step in this direction was made by MacGillivray who described the photochemical [2+2] dimerization of 4,4′-di(pyridyl)ethylene molecules, pre-assembled in a cocrystal by template-directed solid-state cocrystallization, into a cyclobutane product [88]. The milling, achieved by shaking a glass vial in a vortex machine, was required for the cocrystallization step, while the broadband UV lamp from a laboratory photoreactor was used to affect the dimerization in the solid state.…”
