Abstract

We synthesised 1,3-Diphenyl-5-pyren-2-yl-4,5-dihydro-1H-pyrazole(DPP) and investigated its optical properties. The structure of DPP was confirmed by GC-Mass and elemental analysis. The absorption and photoluminescent spectra of DPP were measured at both hydrophobic and hydrophilic solvents and by the stokes shifts of DPP Lippert's equation could be applied. The results showed linear relation between $[{\varepsilon}-1/2{\varepsilon}+1)-(n^2-1/2n^2+1)]$ and $({\mu}_g\;-\;{\mu}_2)^2$.
