1′-biphenyl]-4-amine (4-PIPCFTPA) were designed and synthesized. The fluorophores were structurally characterized by spectroscopic methods. These fluorophores are tharmally stable with thermal decomposition temperature (Td) of ∼446 °C. The photophysical, electronic (theoretical), electrochemical (CV), and electroluminescene properties were thoroughly investigated, the N1 substituted moieties are play a vital
