Organic radicals are attracting increasing interest as a new class of molecular emitters. They
demonstrate electronic excitation and relaxation dynamics based on their doublet or higher …

Organic molecules with high-spin ground states, besides being fundamentally interesting,
possess numerous potential applications in diverse fields such organic magnetism, MRI …

1, n-Dihaloalkanes can be photochemical precursors of n-haloalkyl and-allyl radicals and
cations, which are generated via one-photon processes. Time-resolved techniques have …

Organic molecules with a strong preference for triplet ground states, in which the triplet state
is below the lowest singlet state by≥ 10 kcal/mol, are typically short-lived and mostly …

The photochemistry of reactive intermediates has been an area of increasing interest over
the last 10 years. 2" 7 Much of this interest has been prompted by the fact that laser-initiated …

We describe synthesis and characterization of a derivative of aza-m-xylylene, diradical 2,
that is persistent in solution at room temperature with the half-life measured in minutes (∼ …

A new efficient synthesis of m-xylylene 1 is reported. The diradical 1 was trapped in argon
matrices at 10 K and characterized by IR, UV− vis, and EPR spectroscopy. The syntheses …

Aminyl diradical 3, a derivative of aza-m-xylylene, is expected to be more stable than
diradical 1, due to increased steric protection of the radicals by additional methyl groups in …

Triplet diradicals have attracted tremendous attention due to their promising application in
organic spintronics, organic magnets and spin filters. However, very few examples of triplet …

Photodissociation of o-xylene in room temperature «-heptane solution has been studied by
means of two-pulse laser-induced fluorescence and transient absorption spectroscopy …
