Usage

General Description

(E,E)-4,4'-Bis[2-(4-methoxyphenyl)ethenyl]-2,2'-bipyridine, also known as DPIP, is a chemical compound commonly used as a redox indicator in biochemical assays. It is a member of the viologen family of compounds, which are characterized by their ability to undergo reversible redox reactions. DPIP is frequently utilized in photosynthesis research to measure the rate of electron transport in chloroplasts, as it changes color from blue to colorless when it accepts electrons. This makes it an important tool in studying the process of photosynthetic electron transport and the activity of various enzymes involved in this process. Additionally, DPIP is also used in other biochemical assays to study redox reactions and enzyme kinetics.

Rationally designed ruthenium complexes for 1- and 2-photon photodynamic therapy

The use of photodynamic therapy (PDT) against cancer has received increasing attention over recent years. However, the application of the currently approved photosensitizers (PSs) is limited by their poor aqueous solubility, aggregation, photobleaching an

One- and Two-Photon Phototherapeutic Effects of RuII Polypyridine Complexes in the Hypoxic Centre of Large Multicellular Tumor Spheroids and Tumor-Bearing Mice**

During the last decades, photodynamic therapy (PDT), an approved medical technique, has received increasing attention to treat certain types of cancer. Despite recent improvements, the treatment of large tumors remains a major clinical challenge due to th

Synthesis, characterization, spectroscopic and electrochemical studies of donor-acceptor ruthenium(II) polypyridine ligand derivatives with potential NLO applications

In this work we report the preparation of six new donor-metal-acceptor (D-M-A) type complexes of ruthenium(II) with the highly absorbing chromophoric ligand 4,4′-bis(2-(4-methoxyphenyl)styryl)-2,2′-bipyridine, (L-OCH3, donor moiety) and substituted polypyridinic ligands with electron acceptor character (NN-A). The NN-A studied ligands were pyrazino[2,3-f][1,10]phenanthroline (ppl), 11-R-dipyrido[2,3-a:2′,3′-c]phenazine (dppz-R; R is H, NO2, or CN) and 10,11-[1,4-naphtalenedione]dipyrido[3,2-a:2′,3′-c]phenazine (Aqphen). The complexes were characterized by IR, NMR, UV-Vis spectroscopy and cyclic voltammetry. The potential NLO response of the complexes was evaluated by solvatochromic studies. Although the communication between D and A exists, the effect of the change of the acceptor moiety on the properties of the complexes is small and the behavior of the complexes is governed mainly by the donor ligand. The Metal to Ligand Charge Transfer bands (MLCT) exhibited by all complexes in the visible region have dominant electronic density transfer character from the metal to the chromophoric L-OCH3 ligand. The hypsochromic shift of this low energy absorption band on going from a less polar (benzene) to a more polar solvent (acetonitrile) indicated that a redistribution of the electronic density among the metal and the donor ligand is observed. This behavior permits to predict a NLO response for these types of complexes. The combination of high molar absorptivity with intraligand charge transfer (ILCT) mixing into the MLCT bands are encouraging for the generation of new materials with interesting NLO properties.
