Synthesis and excited-state photodynamics in perylene-porphyrin dyads 2. Effects of porphyrin metalation state on the energy-transfer, change-transfer, and deactivation channels
Article Abstract:
The photophysical properties of two perylene-porphyrin dyads are examined in detail with the aim of expanding the functional utility of these constructs for molecular optoelectronics applications. The study indicate that perylene-bis(imide) dye diphenylethyne free base porphyrin (PDI-pep-Fb) has the greatest potential utility in photonics applications wherein light harvesting by an accessory pigment, energy transport to an output chromophore, and emission are desired.

Synthesis and excited-state photodynamics of perylene-porphyrin dyads. 1. Parallel energy and charge transfer via a diphenylethyne linker
Article Abstract:
The photo physical properties of a perylene-porphyrin dyad are examined with the aim of using this construct for molecular photonics applications. The study investigates the use of perylene-imide dyes as accessory pigments with porphyrins, using a longer linker than in Wasielewski's phenyl-linked system in an attempt to suppress electron-transferquenching while maintaining energy transfer.

Resonance Raman characterization of excitonically coupled meso, meso-linked porphyrin arrays
Article Abstract:
Resonance Raman (RR) spectra are reported for dimeric, trimeric, and tetrameric porphyrin arrays in which the porphyrins are directly linked at the meso position. The studies of the meso, meso-linked arrays, provide insight into the type of RR scattering that might be anticipated for other types of systems that exhibit strong excitonic interactions among the constituents.
