Near-edge X-ray absorption fine structure spectra of three pyrimidine (viz., cytosine, uracil, and thymine) and two purine (viz., adenine and guanine) nucleobases, which are the key constituents of DNA and RNA, were measured at the C, N, and O K-edge

Whereas static conductance of molecules arranged in self-assembled monolayers has been extensively studied, little is known about the dynamics of the charge transfer in these systems. By the example of alkanethiolate films, we show that the latter ph

Interactions of thermally and electronically stimulated reactions in thin layers on surfaces are investigated. For self-assembled monolayers, thermal activation promotes many processes primarily induced by electronic excitations. We demonstrate that

Self-assembled monolayers (SAMs) can undergo an exchange-reaction with the molecules capable of building a SAM on the same substrate upon the immersion into the respective solution. However, for most systems, the exchange reaction is very slow at nor
