General description
Cyclooctatetraene is an 8p electron system and has a triplet ground state if the p electrons are delocalized. It is antiaromatic hence highly unstable and reactive. It adopts a non-planar boat conformation to attain stability with alternating single and double bonds and hence behaves like a polyolefin.
Cyclooctatetraene (COT) is a nonaromatic 4n π-conjugated system with a non-planar tub-shaped geometry and potential energy surfaces at the ground state.
Application
COT may be functionalized by two side groups which can be used as active anode materials for rechargeable batteries. High capacity and voltage organic cathodes may be developed by using COT that can be fused with carbon molecules.
- Used in the synthesis of highly organic film for silicon surfaces to improve its chemical and physical properties.
- Used in liquid state organic dye lasers.
- Used as triplet state quencher to reduce dye blinking.

Neuronal mRNAs can be packaged in reversibly stalled polysome granules before their transport to distant synaptic locales. Stimulation of synaptic metabotropic glutamate receptors (mGluRs) reactivates translation of these particular mRNAs to produce plasticity-related protein; a phenomenon exhibited during mGluR-mediated LTD.

Membrane proteins such as ion channels and transporters are frequently homomeric. The homomeric nature raises important questions regarding coupling between subunits and complicates the application of techniques such as FRET or DEER spectroscopy. These challenges can be overcome if the

The first step in DNA mismatch repair (MMR) is the recognition of DNA mismatches or nucleotide insertions/deletions (IDLs) by MutS and MutS homologues. To investigate the conformational properties of MutS-mismatch complexes, we used single-molecule fluorescence resonance energy transfer (smFRET) to
