Synthesis and Photo Electrochemical Characterization of an Extended π-Conjugated Heteroleptic Ruthenium (II) Complex

Submit Manuscript | http://medcraveonline.com efficiencies of >10% for metal free dyes, >11% for metal complex and 13% for porphyrin based sensitizers [1-6]. As sensitizers take part in the absorption of solar radiation and injection of electrons into the conduction band of semiconductors, extensive research has been focused on the design of efficient and durable sensitizers. Several dyes have ...

Supramolecular Assemblies of Cucurbiturils with Photoactive, π‐conjugated Chromophores

Supramolecular assemblies of cucurbituril (CBn) homologues with p-conjugated chromophores will be overviewed. Special emphasis will be given to the effect of CBn on the optical properties of conjugated oligomers and polymers. How supramolecular complexes of p-conjugated chromophores including porphyrin derivatives, conjugated oligomers and polymers with CBn could be utilized in the theranostic ...

Cooperative enhancement of optical nonlinearities in a porphyrin derivative bearing a pyrimidine chromophore at the periphery.

A novel porphyrin derivative bearing one D-π-A-π-D pyrimidine chromophore at the periphery was designed, prepared, and studied using the Z-scan technique, the results showing that this compound exhibits enhanced nonlinear optical (NLO) absorption, refraction and optical limiting responses. The significant NLO properties can be ascribed to an effective combination of distinct nonlinear mechanisms.

Charge Transfer Enhancement in the D-π-A Type Porphyrin Dyes: A Density Functional Theory (DFT) and Time-Dependent Density Functional Theory (TD-DFT) Study.

The electronic geometries and optical properties of two D-π-A type zinc porphyrin dyes (NCH₃-YD2 and TPhe-YD) were systematically investigated by density functional theory (DFT) and time-dependent density functional theory (TD-DFT) to reveal the origin of significantly altered charge transfer enhancement by changing the electron donor of the famous porphyrin-based sensitizer YD2-o-C8. The molec...
