PET suppression of acridinedione dyes by urea derivatives in water and methanol
Article Abstract:
Absorption, steady-state fluorescence and time-resolved fluorescence measurements are used to investigate the interaction of acridinedione dyes with urea and its derivatives in water and methanol. The hydrophobic interaction of dye with urea in aqueous solution predominates due to the weakening of the hydrogen bonding of the solvent and urea derivatives and the photoinduced electron transfer (PET) process is used as a marker to identify the hydrophobic interaction.

Simulation of the electron transfer between the tetraheme subunit and the special pair of the photosynthetic reaction center using a microstate description
Article Abstract:
The kinetics of the charge-transfer systems are formulated in a microstate form to understand the simulations of the electron transfer between the tetraheme subunit and the special pair of the photosynthetic reaction of the proteins. The analysis reveals that the electron-transfer rate constants can be easily obtained by using the combination of the various electrostatic calculations with the existing empirical rate law.

Photoinduced energy and electron transfer processes in hexapyropheophorbide a-fullerene [[C.sub.60]] molecular systems
Article Abstract:
The photophysical properties of the novel hexapyropheophorbide a (P6) and hexakis (pyropheophorbide a)-[C.sub.60] ([FP.sub.6]) are investigated and compared with those of hexakis (pyropheophorbide a)-fullerene [5:1] hexaadduct (FHP6). It is observed that after light absorption the pyropheophorbide molecules in all three compounds undergo very efficient energy transfer as well as partly excitonic interactions.
