For Newkome-type first, second and third generation dendrimers with t-butyl end groups and a pyrene moiety attached to the core, excimer emission in aqueous solutions indicates aggregation, but the excimer formation is hindered by the size of the dendrimer.

Rhodamine 123 fluorescence (green) can be used to asess cell viability in photosensitized experiments where the intracellular lifetime of singlet oxygen is measured. The porphyrin used as the sensitizer tends to localize in the nucleus when incorporated into a cell (orange).

Issue 6, 2007

The photochemistry of alkyl phenylglyoxylates was investigated using time-resolved infrared spectroscopy. The primary focus was on the analysis of weak transient bands around 1828 and 1730 cm?1. The observed transients were assigned to benzoyl and alkyl mandelate ester radicals, respectively.

Luminescence intensity of a Pt(II) complex in the prescence of DNA is a function of DNA/complex ratio. For smaller ratios (surface binding), Pt(II) complex luminescence increases and at higher ratios (intercalation) complex luminescence decreases as electron transfer from guanine sites becomes predominant.
