چکیده
Meso-substituted borondipyrromethene (BODIPY)-porphyrin compounds that include free base porphyrin with two different numbers of BODIPY groups (BDP-TTP and 3BDP-TTP) were designed synthesized to analyze intramolecular energy transfer mechanisms meso-substituted BODIPY-porphyrin dyads the effect connected free-base on mechanism. Absorption spectra conjugates showed wide absorption features in visible region, is highly valuable increase light-harvesting efficiency. Fluorescence studied proved emission intensity decreased upon photoexcitation core, due from unit porphyrin. In addition, ultrafast pump-probe spectroscopy measurements indicated 3BDP-TTP compound (about 3 ps) faster than BDP-TTP 22 ps). Since core directly binds unit, rapid was seen for both compounds. Thus, rate increased an increasing number moiety

Ultrafast decay of the excited singlet states of thioxanthone by internal conversion and intersystem crossing.
The experimental ultrafast photophysics of thioxanthone in several aprotic organic solvents at room temperature is presented, measured using femtosecond transient absorption together with high-level ab initio CASPT2 calculations of the singlet- and triplet-state manifolds in the gas phase, including computed state minima and conical intersections, transition energies, oscillator strengths, and ...
متن کاملNanomagnetic control of intersystem crossing.
A theory is presented for how magnetic nanostructures can catalyze intersystem crossing in molecular radical pairs. Magnetic field gradients near physically realistic nanostructures are strong enough to induce a relative reorientation of two electronic spins in <1 ns, overwhelming nuclear hyperfine coupling as a driver of intersystem crossing. Nanomagnetic control of intersystem crossing repres...
متن کاملThioxanthone in apolar solvents: ultrafast internal conversion precedes fast intersystem crossing.
The photophysics of thioxanthone dissolved in cyclohexane was studied by femtosecond fluorescence and transient absorption spectroscopy. From these experiments two time constants of ∼400 fs and ∼4 ps were retrieved. With the aid of quantum chemically computed spectral signatures and rate constants for intersystem crossing, the time constants were assigned to the underlying processes. Ultrafast ...
متن کاملUltrafast intersystem crossing dynamics in uracil unravelled by ab initio molecular dynamics.
Ab initio molecular dynamics simulations have been performed in order to investigate the relaxation dynamics of uracil after UV excitation in gas phase. Intersystem crossing (ISC) has been included for the first time into time-dependent simulations of uracil, allowing the system to relax in the singlet as well as in the triplet states. The results show a qualitatively different picture than sim...
متن کاملUltrafast intersystem-crossing in platinum containing π-conjugated polymers with tunable spin-orbit coupling
The development of efficient organic light-emitting diodes (OLED) and organic photovoltaic cells requires control over the dynamics of spin sensitive excitations. Embedding heavy metal atoms in π-conjugated polymer chains enhances the spin-orbit coupling (SOC), and thus facilitates intersystem crossing (ISC) from the singlet to triplet manifolds. Here we use various nonlinear optical spectrosco...
