Abstract
A drop in melting point of 21.5°C is induced by the UV-photolytic trans→cis isomerization of the duplex formed between an oligonucleotide bearing two D-threoninol-tethered azobenzene moieties in the side chain and its complementary counterpart. On irradiation with visible light, the dissociated single-stranded oligonucleotides regenerate the duplex.
