The excited state dynamics of a structurally flexible push–pull stilbene, namely, trans-4-(N,N-dimethylamino)-4′-nitrostilbene (DMANS), in solvents of varying polarities, H-bonding abilities and viscosities, has been investigated using femtosecond transient absorption spectroscopic technique. Results of DFT and TDDFT calculations have been used to explain the experimental data. Following photoexcitation...
Using self-consistent field calculations and scaling analysis, we determined the property of polymers that are tethered onto impenetrable, solid surfaces or adsorbed onto penetrable interfaces. In the case of impenetrable solids, we consider homogeneous walls, as well as surfaces containing chemically distinct patterns. These findings provide guidelines for tailoring the morphology of the polymer...
