The top schematic shows an overview of the study, including photodimerization
of the fluorescent AC monomer to the Di-AC particle mechanophore, followed by incorporation of the particles into a polyurethane matrix, with subsequent compression for the fluorescent mechanochemical activation.
hospitals uses four techniques: photohydration, causing functional damage by inserting water into cellular structures; photosplitting, splitting the phosphate backbone of the DNA; photo crosslinking, creating bonds among protein molecules that lead to structural damage; and photodimerization
, the bonding of the elements of DNA and RNA.
This study demonstrates a unique approach to regio- and enantiocontrolled [2+2] photodimerization
reactions in molecular crystals.
Part two contains chapters on cyclobutarenes; organometallic derivatives; synthesis and reactivity in the photochemistry of cyclobutanes; photodimerization
of crystalline olefins in the solvent-free photosynthesis of cyclobutanes; chemistry of cubane and other prismanes; bicyclo[2.
Work will continue on the synthesis of ligands for use in the production of new porous materials through solid state photodimerization
of the vinyl groups.
In a nice twist, chiral, optically pure oxazolines on the periphery of the thiophenes control the self-assembly to give dimers of only one helical chirality, and this helical chirality controls the photodimerization
to give essentially only one diastereomer (see opposite).

So the photo-crosslinking is hindered by the surrounding in the aggregation, effective photodimerization
cannot be observed.
