The synthesis and spectral properties of novel 4-phenylacetylene-1,8-naphthalimide derivatives

摘要: Abstract A series of novel N -alkyl-1,8-naphthalimide derivatives with phenylacetylene at the C-4 position were synthesized using 4-bromo-1,8-naphthalimides and arylacetylenes as starting materials in presence Pd(PPh 3 ) 2 Cl /CuI under mild conditions. The absorption fluorescence properties these compounds recorded quantum yields measured DMF solution quinine sulphate standard. It was found that UV/vis range 372–399 nm emission between 428 531 nm. Substituent effects on spectra are discussed.
