Multichromophoric dendrimers as single-photon sources: A single-molecule study

Article Abstract:

Single-molecule fluorescence spectroscopy is performed on a number of multi-peryleneimide substituted polyphenylene dendrimers for the purpose of investigating the parameters, which influence the efficiency of the dendrimers as single-photon sources at room temperature. Analysis of fluorescence intensity, lifetime, and interphoton arrival time distribution revealed that all measured first-generation dendrimers behave as single-photon emitters.

Excited-state dynamics in the enhanced green fluorescent protein mutant probed by picosecond time-resolved single photon counting spectroscopy

Article Abstract:

The study was done on the complexphotophysics of the wild-type green fluorescent protein (GFP) by means of a model implying excited-state proton transfer (ESPT) and three forms of chromophore. A systematic picosecond time-resolved fluorescence study of the enhanced green fluorescent protein (EGFP) variant is reported, carrying the Ser65-Thr and Phe64-Leu mutations.
