Sentence examples for meso position of from inspiring English sources

The SKPor-1 dye has large red-shift of the absorption maxima due to introduction of the dimethylaminophenyl moiety at the meso position of the porphyrin ring.

For the BODIPY series, the 5-quinoline fragment was either introduced at the meso position of the π-conjugated core via a pyrrolic condensation or at the 3,5 positions through Knoevenagel condensations.

A BODIPY based NIR turn-on fluorescent probe (1) carrying a 7-nitro-2,1,3-benzoxadiazole 7-nitro-2,1,3-benzoxadiazole 7-nitro-2,1,3-benzoxadiazole 7-nitro-2,1,3-benzoxadiazole self-immolative liNBDr was designed and successfully constructed.

We have designed and synthesized novel zinc porphyrin dyes which have a D-π-A system based on porphyrin derivatives containing a triphenylamine (TPA) electron-donating group and a phenyl carboxyl anchoring group substituted at the meso position of the porphyrin ring, yielding the push-pull porphyrins as the most efficient green dye for dye-sensitized solar cell (DSSC) applications.

We show that the attachment of a π-conjugated bridge directly on the meso position of the porphyrin via an ethynyl or ethenyl linkage affords significant electronic coupling both on the ground- and excited-states and that oligophenyleneethynylenes represent suitable spacers to assist charge separation between porphyrins.

Under the photovoltaic performance measurement, the maximum incident photon-to-current conversion efficiency (IPCE) value of the DSSC based on HKK-Por 5 was slightly higher than the efficiencies of the DSSCs based on other HKK-Por dyes due to the introduction of the alkoxy group into the TPA moiety at the meso position of the porphyrin ring.

The structure of Cj-YCC indicated the "western" meso position to be unsaturated, opening up conjugation of the two "western" pyrrole rings, and giving rise to a chromophore related to the one found in bilirubin.

The presence of carbazole substituents in the meso positions of the tetrapyrolic macrocycle allows the formation of conducting polymers by coupling of electrogenerated carbazole radical cations.

The polymerization process is based on a nucleophilic attack of the pyridyl nitrogen atoms at the meso positions of the electrogenerated dication porphyrins.

The synthesis of new chromophore architectures based on arrays of phenothiazine and (hetero aromatic units joint in the meso positions of a porphyrin core (phenothiazinyl A4, phenothiazinyl and (hetero aryl: AB3 trans-A2B2 and A3B), is described.

The results show that fusion of a π-conjugated aromatic ring with the pyrrole rings of porphyrin can cause the larger red-shifts in the Q-bands than π-conjugated groups in the meso positions of porphyrin do.
