  avoiding undesirable solvents which are typically employed for such reactions (e.g.DMF). Under optimised conditions, the synthesis of amides in the presence of both primary and secondary alcohol functions was achieved in high to excellent yields (65–94%). Overall, the methods described have significant practical advantages over conventional approaches based upon bulk solvents including greater yields

  Molecular recognition is fundamental to the specific interactions between molecules, of which the best known examples are antibody antigen binding and cDNA hybridization. Reversible manipulation of the molecular recognition events is still a very challenging topic, and such studies are often performed at the molecular level. An important consideration is the collection of changes at the molecular level to provide macroscopic observables. This research makes use of photoresponsive molecular recognition for the fabrication of novel photoregulated dynamic materials. Specifically, a dynamic hydrogel was prepared by grafting azobenzene-tethered ssDNA and its cDNA to the hydrogel network. The macroscopic volume Of the hydrogel can be manipulated through the photoreversible DNA hybridization controlled by alternate irradiation of UV and visible light. The effects of synthetic parameters including the concentration of DNA, polymer monomer, and permanent cross-linker are also discussed.

  An aerolysin nanopore interface was introduced as a molecular machine to electrically read out the real-time photo-controlled motion of an azobenzene-geared DNA train with high spatial and temporal resolution. Under alternating UV and visible irradiation, each DNA train performed two regulated speeds of 1.9 and 6.3 bases/s corresponding to trans and cis states, respectively, with readily identified current signals. Each train type fell into the ultra-narrow current population with a full-width half maximum of 0.2-0.4 pA. The combination of a model molecular machine system and powerful aerolysin interface enabled the motions of every artificial molecular machine to be followed in real time.
