Triplet exciton transport in isotopic mixed naphthalene crystals. I. Kinetic analysis of trapping and fusion
Time-resolved triplet exciton transport in binary mixed crystals has been studied for CHin CloDg (20%-100%) at liquid helium temperatures. The delayed fluorescence decays ar~o g ~xponential and range from milliseconds to nanoseconds as Cg goes from 0.2 to 1.0. The analysis IS based on the presence of a BMN supertrap in large amounts (103) and on the fact that supertrapping.o~ th~ guest ex~itons...
متن کاملTriplet exciton transport in isotopic mixed naphthalene crystals . II . Master equation analysis
The experimental data on triplet exciton transport in isotopically mixed crystals of naphthalene/ perdeuteronaphthalene (paper I) are contrasted with singlet exciton transport in the same samples (20%-100%) and analyzed in terms of incoherent hopping models. The master equation approach is emphasized and extended. We modify the conventional continuum master equations via a physically plausible ...
متن کاملEsr Triplet Exciton Spectrum of Acridine Orange
The triplet state of acridine orange dissolved in methanol/water matrix was investigated by ESR. In absence of oxygen a strong temperature dependence of the spectra was observed. At low temper ature (100 °K) the zero-field splitting parameters calculated from the triplet spectrum are: X /h c = 0.0050 cm-1 , Y / h c = 0.0342 cm-1 , Z //ic = 0.0387 cm-1 , at higher temperature (140 °K) : X * ( h...
متن کاملNaphthalene dimer: Electronic states, excimers, and triplet decay
Computations have been performed for the singlet and triplet electronic states of varying orientations of naphthalene dimer. The dependence of exciton splitting upon orientation and intermonomer distance was explored. Splittings of triplet states are seen to be nontrivial at typical bonding distances, commensurate with the splittings of weakly allowed singlet states. Charge-transfer interaction...
متن کاملNegative polaron and triplet exciton diffusion in organometallic "molecular wires".
The dynamics of negative polaron and triplet exciton transport within a series of monodisperse platinum (Pt) acetylide oligomers is reported. The oligomers consist of Pt-acetylide repeats, [PtL(2)-C≡C-Ph-C≡C-](n) (where L = PBu(3) and Ph = 1,4-phenylene, n = 2, 3, 6, and 10), capped with naphthalene diimide (NDI) end groups. The Pt-acetylide segments are electro- and photoactive, and they serve...
