Fluorescence Correlation Spectroscopy as a Quantitative Tool Applied to Drug Delivery Model Systems [PDF]

open access: yes, 2010
The delivery of drugs to cells is a very active area of research. Drugs are commonly believed to ameliorate illnesses. The targeted, controlled and/or enhanced uptake of the drug into cells is facilitated by loading the drug into carrier vehicles ...

Liquid Crystalline Perylene Bisimide Assemblies

open access: yes, 2019
Das Hauptaugenmerk dieser Arbeit war daher darauf gerichtet, eindimensionale flüssigkristalline J-Aggregate zu erzeugen und zu untersuchen, die eine vollkommen neue Anordnung von Perylenbisimiden aufweisen und deren Übergangsdipolmomente parallel zur Säulenachse ausgerichtet sind.

Xylylene Bridged Perylene Bisimide Cyclophanes and Macrocycles [PDF]

open access: yes, 2017
This work is concerned with the syntheses and photophysical properties of para-xylylene bridged macrocycles nPBI with ring sizes from two to nine PBI units, as well as the complexation of polycyclic aromatic guest compounds. With a reduced but substantial fluorescence quantum yield of 21% (in CHCl3) the free host 2PBI(4-tBu)4 can be used as a dual ...
