Aggregation and induced chirality of an anionic meso-tetraphenylsulfonato porphyrin (TPPS) on a layer-by-layer assembled DNA/PAH matrix

Article Abstract:

A study on the aggregation and induced chirality of an anionic meso-tetraphenylsulfonato porphyrin (TPPS) on a layer-by-layer assembled deoxyribonucleic acid/poly (allylamine hydrochloride) (DNA/PAH) film is conducted. The results revealed that TPPS could directly penetrate into a DNA/PAH film and be assembled in both H-aggregates and J-aggregates, and showed strong induced circular dichroism (CD) in the film.

Characterization of a porphyrin-containing dye-sensitized solar cell

Article Abstract:

The photovoltaic performance of several porphyrin-derivatized TiO2 films in regenerative photoelectrochemical cells is reported and compared to that in cells sensitized with a Ru(2,2'-bipyridyl-4, 4E-dicarboxylate)2(NCS)2(N3) dye. The N3 and TCPP dyed generated very high IPCE values compared to TDTBPP and ZnTDTBPP.

Contributions of a long side chain to the binding affinity of an anthracene derivative to DNA

Article Abstract:

A systematic study was conducted on the DNA binding of a new anthracene derivative, which carries a 1,8-octyldiamine side chain. This binding of the DNA is reversible, and depends on the ionic strength, and the major binding mode is suppressed at high ionic strengths and a new mode begins to dominate the binding.
