Novel soluble and thermally-stable fullerene dyad containing perylene

, p. 1849 - 1853 (2004)
A novel fullerene dyad C60-P1 in which a perylene moiety is attached to C60 through a pyrrolidine ring has been prepared by 1,3-dipolar cycloaddition of the azomethine ylides generated in situ from the corresponding aldehyde and sarcosine. Electrochemical and photophyscial studies of the dyad in solution have revealed that there is no significant ground-state electronic interaction between the covalently bonded perylene moiety and the fullerene. The photophysical investigations have also shown that there exists an effective photoinduced energy transfer from the perylene moiety to C 60. A photovoltaic device made with the dyad has confirmed that photoinduced electron transfer does take place within the dyad; however, the efficiency of the electron transfer is negligible relative to the energy transfer.

-
Paragraph 0415; 0416, (2015/03/13)
The invention relates to a light harvesting array or dye comprising an acceptor linked to a donor, wherein at least one of the acceptor or the donor is an oligomeric unit comprising a first optionally substituted rylene linked via a linker group to a second optionally substituted rylene, the first optionally substituted rylene is linked to the acceptor or the donor and the second optionally substituted rylene is capable of energy transfer to at least one of the first optionally substituted rylene, the acceptor or the donor. The invention also relates to compounds which may be used as light harvesting arrays, methods for their manufacture, and devices and materials comprising the light harvesting array or dye, for example, chromophoric materials, light guides, photobioreactors, photoluminescent algae systems, photodetectors, photovoltaic devices and luminescent/fluorescent solar concentrators.
Synthesis, electrochemical and optical absorption properties of new perylene-3,4:9,10-bis(dicarboximide) and perylene-3,4:9,10-bis(benzimidazole) derivatives

, p. 5427 - 5440 (2011/11/29)
A series of perylene-3,4:9,10-bis(dicarboximide) (PBI) and perylene-3,4:9,10-bis(benzimidazole) (PTCBI) derivatives that are di-or tetra-substituted at the bay region by electron-donating or electron-withdrawing groups have been synthesized as soluble n-type semiconductors. Optical absorption spectroscopy and electrochemical analysis show that the nature of substitution at the bay region plays a crucial role in the modulation of the electronic properties of these PBI and PTCBI derivatives. Examination of these optical and electrochemical data in the light of energy levels identified by theoretical studies allowed a relationship between the structure and the electronic properties to be established. A relationship between the structure and electronic properties of n-type semiconductors from perylene-3,4:9,10- bis(dicarboximide) (PBI) and perylene-3,4:9,10-bis(benzimidazole) (PTCBI) series substituted at the bay region by electron-donating or electron-withdrawing groups has been established by using the complementary techniques of absorption spectroscopy, electrochemical analysis and theoretical calculations.
