N2 - The spectroscopic parameters of 4,7-bis(2-thienyl)-1,2,5-oxadiazolo[3,4-c]pyridine (DTOP) were determined which was designed as a red-emitting dye for the electroluminescent (EL) device. The main optical transition of DTOP is attributable to 1La, and therefore, the fluorescence maximum shifted to the red side to reach to 630 nm according to the solvents. Although the non-radiative transition rate was enhanced, when the fluorescence maximum shifts to the longer than 610 nm, DTOP maintains the higher radiation transition probability.
