Spectroscopic properties and site origin of Shpol'skii system—terrylene in n-nonane

High resolution laser induced fluorescence excitation spectroscopy of jet-cooled terrylene

“…We estimated the first electronic transition of free terrylene to be at 19 203 cm À1 by extrapolation the data of terrylene in argon and neon in [6]. With a similar procedure Biktchantaev et al [7] estimated the transition energy for free terrylene to be at 19 181 (±160) cm À1 .…”

“…Due to their interesting photophysics oligorylenes have been extensively studied in the solid and liquid phase in the past few years [1][2][3][4][5][6][7]. The most spectacular experiments detect the fluorescence of single terrylene molecules in a crystal [8][9][10].…”

“…The single molecule spectra are affected by the crystal environment and hence some characteristics of the molecule, e.g., the energy of the S 0 fi S 1 transition, can only approximately be determined. The influence of the molecular environment can be kept small, if the molecules are placed in noble gas matrices (matrix-isolation spectroscopy MIS), which has been demonstrated for terrylene and perylene [6,7]. Other important molecular parameters, such as the moments of inertia cannot be determined in solids.…”

Fluorescence Studies of Terrylene in a Supersonic Jet: Indication of A Dark Electronic State Below the Allowed Transition

“…It is known that the allowed S 0 (1 1 A g ) f S 1 (1 1 B 1u ) transition involves progressions of several totally symmetric vibrations a g , such as the long axis stretch at a frequency [1][2][3][4][5][6][7][8] of ∼240 cm -1 . The fluorescence S 1 (1 1 B 1u ) f S 0 (1 1 A g ) of terrylene taking place from a state well separated from the other excited electronic states has a large fluorescence quantum yield ∼0.74.…”

Facile synthesis of terrylene and its isomer benzoindenoperylene

“…8 These features make it promising for high-tech applications in organic light-emitting diodes and field-effect transistors. 6 Terrylene was also studied as a dopant for single molecular spectroscopy in many organic hosts, such as polymers, 9 Shpol'ski matrices, 10 and single crystals. 7,11 Although the synthesis of terrylene has been described in several papers, 1,[12][13][14][15][16][17] a high yielding method is not yet available.…”
