Time-dependent theory of electronic spectroscopy
(Elsevier, 2021)The time-dependent theory of electronic spectroscopy provides an intuitive approach to understand and quantitatively analyze absorption, luminescence and resonance Raman spectra beyond vertical transition energies. The approach can be combined with ... -
Electronic absorption spectroscopy
(Elsevier, 2021)Absorption spectroscopy in the ultraviolet, visible and near-infrared (UV-VIS-NIR) wavelength ranges is one of the oldest and most often used characterization methods in coordination chemistry. This overview illustrates examples ranging from four-coordinate ... -
In situ photocontrol of block copolymer morphology during dip-coating of thin films
(American Chemical Society, 2015-09-28)We demonstrate a unique combination of simultaneous top-down and bottom-up control of the morphology of block copolymer films by application of in situ optical irradiation during dip-coating. A light-addressable and block-selective small molecule, ... -
Influence of supramolecular interaction type on photoresponsive azopolymer complexes : a surface relief grating formation study
(American Chemical Society, 2016-06-24)The influence of the supramolecular interaction type—hydrogen bonding, proton transfer, and pure ionic bonding—on photoresponsive behavior, particularly surface relief grating (SRG) inscription, has been investigated using a homopolymer with an ambient ... -
Orientation and partial disentanglement in individual electrospun fibers : diameter dependence and correlation with mechanical properties
(American Chemical Society, 2015-06-29)Electrospun fibers are versatile materials that exhibit unusual and tunable properties when studied at the single fiber level, including an exponential increase in modulus with a decreasing diameter toward the nanoscale. Understanding the detailed ... -
Metal–ligand interactions and salt bridges as sacrificial bonds in mussel byssus-derived materials
(American Chemical Society, 2016-09-02)The byssus that anchors mussels to solid surfaces is a protein-based material combining strength and toughness as well as a self-healing ability. These exceptional mechanical properties are explained in part by the presence of metal ions forming ... -
Bridging the gap between the mesoscopic 2D order–order transition and molecular-level reorganization in dot-patterned block copolymer monolayers
(American Chemical Society, 2016-11-21)Langmuir–Blodgett (LB) films of amphiphilic block copolymers (BCs) form well-defined nanostructures with long-range order useful, for instance, for nanolithography applications. Nanostructures with a 2D circular micelle (“dot”) morphology are known to ... -
Photoactive/passive molecular glass blends : an efficient strategy to optimize azomaterials for surface relief grating inscription
(American Chemical Society, 2016-12-15): Irradiation of azomaterials causes various photophysical and photomechanical effects that can be exploited for the preparation of functional materials such as surface relief gratings (SRGs). Herein, we develop and apply an efficient strategy to ... -
Glass versus crystal : a balancing act between competing intermolecular interactions
(American Chemical Society, 2017-04-14)Hydrogen (H) bonds can be used either for crystal engineering or for designing compounds capable of forming very stable glassy phases. Herein, a second type of directional noncovalent interaction, π–π stacking, is introduced to establish the interplay ...
