Dendrimer pattern formation in evaporating drops

Article Abstract:

The analysis of the patterns formed on mica substrates by evaporating small droplets of pentanol containing three different but closely related poly(amidoamine) PAMAM dendrimer molecules dispersed in solution is presented. The morphology of condensed molecule-based ring patterns formed by evaporation of microdroplets on surfaces is used as a fingerprint to identify solute molecule surface chemistry and concentration and function as a sensor for a variety of biochemical events.

The class II/III transition electron on an infrared vibrational time scale for N,N'-diphenyl-1,4-phenylenediamine structures

Article Abstract:

The Marcus-Hush theory and a Bloch-type equation analysis were used to investigate the electron-transfer rates of N,N'-diphenyl-1,4-phenylenediamine (PDA) derivatives in the mixed-valence (MV)state. The PDA derivatives of IV-CT in classes II and III are demonstrated by the introduction of a substituent into the inner or outer phenyl rings.

Up-converted emission in a series of phenlazomethine dendrimers with a porphyrin core

Article Abstract:

The nonlinear optical and time-resolved properties of a series of phenylazomethine--porphyrin dendrimers are reported. Measurements were carried out with the basic building-block molecules and time-resolved measurements suggested efficient intramolecular vibrational energy redistributions in the system.
