Photochromism is defined as a reversible transformation of a chemical species between two
isomers having different absorption spectra induced in one or both directions by …

Molecular switching has established itself as a key functionality of building blocks developed
for addressable materials and surfaces over the last two decades. Many challenges in their …

Recent progress in the field of single‐and two‐photon nanofabrication, both 2‐and 3‐
dimensional, in photopolymerizable resins and in films of photoisomerizable azopolymers …

The second-order nonlinear optical properties of green fluorescent proteins (GFPs), such as
the photoswitchable Dronpa and enhanced GFP (EGFP), have been studied at both the …

We report on the nonlinear optical properties measurements and quantum-chemical
calculations of a well-known photochromic system consisting of spiropyran and the …

We present the first report of two-photon induced plastic surface deformation in solid
polymer films. Exposure of azo polymer films, which absorb in the visible range (λ_max= 480 …

In the present contribution Density Functional Theory (DFT) has been applied to explore
molecular dipole moment, frontier molecular orbital (FMO) features, chemical hardness, and …

The study of fundamental properties of single layers of molecules on gold under various
conditions, mainly the influence of pH and electrode potential, is the focus of this thesis. We …

Recovery speed of photoinduced third-harmonic (TH) generation in azo-copolymer thin films
can be controlled by a nanosecond laser excitation. When the excitation is tuned on, the TH …

We review our work on nanopatterning in azo-polymer films by single, two-and multi-
phopton driven molecular motion in solid bulk polymer. It is now known that light induced …
