Abstract:

Phosphorescence decay curves for 10 polycyclic aromatic sulfur heterocycles (PASHs) with molecular weight (MW) 234 at 77K are reported here. Decay curves were collected with the aid of a Fluoromax (Horiba Jobin Yvon) using a pulsed lamp, fiber optic probe, and shpolskii solvents.

Purpose:

To identify the compounds by their lifetimes.

Data Parameters and Units:

column 1 = X is time (millisecond) column 2 = Y is intensity (cps) csv file: initial delay (milliseconds), sample window (milliseconds), time between flashes (milliseconds), delay increment (milliseconds), maximum delay (milliseconds) Wavelength range = 200-700nm, Flash count = 1, Bandpass = 4nm File naming convention example: 500_ppb_ P910T_77K_lifetime where 500 = concentration value of polycyclic aromatic sulfur heterocycles (PASHs); ppb = concentration unit (parts per billion); P910T = PASH standard where the following code list was used: P32T = Phenanthro (3,2-b) Thiophene P23T = Phenanthro (2,3-b) Thiophene P12T = Phenanthro (1,2-b) Thiophene P21T = Phenanthro (2,1-b) Thiophene P34T = Phenanthro (3,4-b) Thiophene P43T = Phenanthro (4,3-b) Thiophene P910T = Phenanthro (9,10-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 ; lifetime = lifetime of each compound
