Cytosine (Cyt) among all the nucleic acid bases features the most complex and least understood nonradiative deactivation, a process that is crucially important for its photostability. Herein, the excited state dynamics of Cyt and a series of its N1-

A combined method of femtosecond broadband time-resolved fluorescence (fs-TRF) and transient absorption (fs-TA) was employed to investigate the excited state dynamics of 2′-deoxyguanosine (dG) and 2′-deoxyguanosine 5′-monophosphate (dGMP). Comp

An organometallic cyclometalated platinum(II) complex, [Pt(L(3))Cl][PF(6)], has been synthesised from a specially designed cyclometalating ligand, HL(3) (triphenyl{5-[3-(6-phenylpyridin-2-yl)-1H-pyrazol-1-yl]pentyl}phosphonium chloride), that contain
