Optical Properties of 5,5'-(9,9-dioctyl-9H-fluorene-2,7-diyl)Bis(thiophene-2-carbal dehyde): A Novel Organic Light Emitting Material

Abstract:

A novel D-A type molecule based on central fluorene unit and aldehyde group termini has been designed and constructed. Optical spectra show that, from the solution to the solid state, the absorption and fluorescence spectra of the compounds are red-shifted. Moreover, a red-shift of the absorbance maxima and the emission maxima of the compounds were observed due to the electron-accepting groups. Blue light-emitting properties with purity color range at 412–468 nm were also obtained. Thus, the target compound is expected to be a promising pure blue light-emitting material for applications in organic light-emitting diodes (OLEDs).
