New perylenes for dye sensitization of TiO2
Ferrere, Suzanne,Gregg, Brian A.
, p. 1155 - 1160 (2002)
We describe a new generation of perylene photosensitizers based upon N-(2,5-di-tert-butylphenyl)perylene-3,4- dicarboximide. The new sensitizers have more favorable energetics for electron injection into TiO2 and better light absorption properties for solar conversion than previous sensitizers based upon perylene tetracarboxylic acid dianhydride. Syntheses, absorption properties, and electrochemical potentials for the new perylenes are reported. We compare the solar conversion efficiencies of the dyes in the dye sensitized solar cell (DSSC) and discuss trends in terms of energetics and structural differences that may affect the injection and recombination processes. These are the highest efficiencies yet reported for perylene sensitizers in the DSSC.

Paragraph 0050; 0061, (2021/08/14)
The invention discloses a supramolecular compound nano-carrier as well as a preparation method and application thereof, and relates to the technical field of polymer chemistry and biological detection engineering. According to the supramolecular compound nano-carrier disclosed by the invention, a two-dimensional nanosheet supramolecular structure system generated by self-assembly is driven by an anion induction effect, and a supramolecular compound nano-carrier is of a single-layer nanosheet supramolecular structure constructed by a highly-oriented one-dimensional nanorod. A hydrophobic perylene group part is used as a skeleton part for constructing the highly-oriented one-dimensional nanorod, and the charge density of a single-layer nanosheet can be regulated and controlled. The surface of the water-soluble multivalent hydrophilic part can be loaded with DNAzyme deoxyribozyme for specific detection of heavy metal ions through electrostatic interaction, and the water-soluble multivalent supramolecular compound nano sensor is constructed. Based on a fluorescence change mechanism caused by specific cutting of heavy metal ions, The fluorescence detection of the heavy metal ions in food and biological tissues is realized, and the detection effect of the heavy metal ions is greatly enhanced.

Supramolecular light-absorbing nanostructures are useful building blocks for the design of next-generation artificial photosynthetic systems. Development of such systems requires a detailed understanding of how molecular packing influences the material's
