Abstract:

This dataset contains triplicate excitation and emission spectra of polycyclic aromatic sulfur heterocycles (PASHs) with molecular weight (MW) 234 Da used to create smoothed spectra at room-temperature (RT), 77K, and 4.2K for datasets that are available under GRIIDC UDIs R5.x284.000:0009, R5.x284.000:0010, R5.x284.000:0011, R5.x284.000:0013, and R5.x284.000:0014. RT, 77K, and 4.2K excitation and emission spectra were recorded with the aid of a Fluormax (Horiba Jobin Yvon) using shpol'skii solvents and continuous wave lamp. Excitation and phosphorescence spectra were also recorded using pulsed lamp at 77K and 4.2K. Spectra were reported for 6 PASHs (Anthrathiophenes and benzonaphthothiophenes) with molecular weight 234 Da. All measurements were done by using fiber optic probe (FOP).

Purpose:

To identify spectral features of polycyclic aromatic sulfur heterocycles standards with molecular weight 234 Da.

Data Parameters and Units:

column 1 = X is wavelength (nm); column 2, 3, and 4 = S1 is intensity (cps) of triplicate spectra; column 5, 6, and 7 = Intensity of blank emission or excitation in cps; Wavelength range = 200-700nm, integration time = 0.1 sec, band pass = 2nm, step size = 1nm File naming convention example: 7.5_ ppb_ A23bT_77K_ excitation where 7.5 = concentration value of polycyclic aromatic sulfur heterocycles (PASHs); ppb = concentration unit (parts per billion); A23bT = PASH standard where the following code list was used: A23T = Anthra (2,3-b) Thiophene A12T = Anthra (1,2-b) Thiophene A21T = Anthra (2,1-b) Thiophene BbN12T = Benzo (b) naphtho (1,2-b) Thiophene BbN21T = Benzo (b) naphtho (2,1-b) Thiophene BbN23T = Benzo (b) naphtho (2,3-b) Thiophene 77K= temperature of the sample 4.2K = temperature of the sample RT = room-temperature; excitation = spectra type (excitation or emission); Phosphorescence spectra taken under these conditions are included for all of the above compounds with the exceptions of the Anthra group (A12T, A21T, A23T).

Instruments:

Fluoromax (Horiba Jobin Yvon).
