photoinduced

In the case of photoinduced electron transfer the use of time-resolved spectroscopy is common.

Photoinduced molecular transformations at transition metal oxide surfaces can be organized in two general classes.

This receptor-spacer-reporter concept is a recurring theme often with the reporter displaying photoinduced electron transfer.

This nanohybrid showed similar photoinduced electron-transfer processes.

This is also true for rearrangements of 4n + 2 pi (where n is a whole number) electrons driven by light (photoinduced).

This reaction, called photoinduced charge separation, is the start of the electron flow and is unique because it transforms light energy into chemical forms.

He has created models for photoinduced isomerization in retinal, which represents the biophysical basis for vision.

Photoinduced electron transfer is an electron transfer which occurs when certain photoactive materials interact with light.

As with photosystem II and the bacterial reaction centre, a pair of chlorophyll a molecules initiates photoinduced charge separation.

The reverse process to photoinduced electron transfer is displayed by light emitting diodes (LED) and chemiluminescence.

Photoinduced rearrangements of 4n pi electron systems (where the number of electrons is divisible by 4) follow the disrotatory rule.

Cyanobacteria, which reside several meters underwater, cannot receive the correct wavelengths required to cause photoinduced charge separation in conventional photosynthetic pigments.

As a result, the formation of a photoinduced quasiparticle, or polaron (P), occurs on the polymer chain and the fullerene becomes an radical anion (C60).

Conspecific and heterospecific song exposure accelerates photoinduced reproductive development in the flexibly breeding Rufous-winged Sparrow, Aimophila carpalis.

For the photoinduced ring opening of cyclobutene, is it shown that the disrotatory motion predicted by the Woodward-Hoffmann rules is established within the first 50 fs after optical excitation.

Photoclick chemistry utilizes a photoinduced cycloreversion to release N. This generates a short-lived nitrile imine 1,3-dipole which undergoes a 1,3-dipolar cycloaddition with an alkene to generate pyrazoline cycloadducts.

This process results in the formation of a positive charge on the special pair (due to the loss of an electron) and a negative charge on the acceptor and is, hence, referred to as photoinduced charge separation.

Photoinduced charge separation is the process of an electron in an atom or molecule, being excited to a higher energy level by the absorption of a photon and then leaving the atom to a nearby electron acceptor.

Unlike the reaction centers of all other photosystems which have a special pair of closely spaced chlorophyll molecules, the pigment that undergoes the initial photoinduced charge separation in PSII is a chlorophyll monomer.

If arranged correctly, the introduction of a tertiary amine within these supramolecular systems will permit binding to occur at physiological pH and allow signalling mechanisms such as photoinduced electron transfer mediated fluorescence emission to report the binding event.

When a chlorophyll molecule at the core of the photosystem II reaction center obtains sufficient excitation energy from the adjacent antenna pigments, an electron is transferred to the primary electron-acceptor molecule, pheophytin, through a process called photoinduced charge separation.

The development of a donor-acceptor (D-A) interface composed of conducting polymer donors and buckminsterfullerene derivative acceptors create a phase-separated composite that enhances photoconductivity (available with only polymer donors) in the photoinduced charge transfer process of photovoltaic cells.

Once photoinduced charge separation has been initiated, the electron travels down a pathway through a chlorophyll α molecule situated directly above the P700, through a quinone molecule situated directly above that, through three 4Fe-4S clusters, and finally to an interchangeable ferredoxin complex.
