  The mechanically induced melting properties of DNA were employed to achieve force labile membranes is described. Nucleobase pairs were used as mechanophores. Adenine and thymine functionalized complementary amphiphilic block copolymers were self-assembled into polymersomes. The nucleobases formed hydrogen bonds which were disrupted upon force stimulation. The exposure of the disconnected nucleobases to the hydrophobic matrix of the membranes lead to a change of permeability which permitted the exchange of water-soluble molecules throughout the polymer matrix. Moreover, the encapsulation of horseradish peroxidase enabled the reaction of luminol with hydrogen peroxide to yield a luminescence producing species similar to the marine bioluminescence. Moreover, the same nano-reactors were employed to catalyze the formation of a polyacrylamide gel when force was applied. Insights into the change of permeability of supramolecular networks upon force are provided. These systems are useful for drug delivery, as nanoreactors and for the selective release of curing agents for 3D printing, or fragrances.

  A method for synthesizing aromatic compounds by selectively dehalogenating aromatic starting materials is provided. Compounds may be prepared which are substituted with fluoro, chloro or bromo. The method may be used to remove halogen atoms from sites at which halogenation is not desired, and to form substantially pure halogenated compounds from mixtures of starting materials. The method uses a copper containing dehalogenation agent and an acid with the dehalogenation being controlled by a substituent such as a carboxylic acid, amide, ester, aldehyde, ketone or cyano on the aromatic ring.
