We now show that a hydrophobic cavity created within the DNA can work as a scaffold to form a charge transfer (CT) complex composed of naphthalenediimide (NDI) and dialkoxynaphthalene (DAN) derivatives. The formation of the CT complex resulted in ...

Bis(2-thienyl)-diketopyrrolopyrrole having two -cylcens (DPPCy) was synthesized. DPP-aggregates were constructed by self-organization of DPPCy and -DNAs. In the presence of L-ascorbic acid as an electron sacrifice reagent, the DPP a...
Small ligand molecules, which can recognize thermodynamically unstable site within DNA, such as mismatch base pair, abasic site, and single-bulge, have attracted much attention because of their potential diagnostics and biological applications. In...
DNA oligonucleotides possessing naphthalimide (NI) at the C5 position of deoxyuridine through an ethynyl-containing linker have been synthesized. Based on time-resolved laser flash photolysis, we showed that the photo-induced charge transfer occur...

Upon UV-irradiation of alken-1-yl aryl methyl phosphates in methanol a cationic migration of an aryl group to a neighbouring olefinic moiety to produce arylalkanone and arylalken-1-yl methyl ether has been observed.

Upon UV irradiation in acetonitrile, tri-1-naphthyl phosphate and di-1-naphthyl methylphosphonate underwent intramolecular rearrangement and ipso-coupling to give 1,2'-binaphthalen-1'-ol and 1,1'-binaphthalene, respectively. In the photolyses of t...
