✦ Synopsis

Two new derivatives of 4-dicyanomethylene-2,6-dimethyl-4H-pyran were synthesized and characterised. The fluorescence intensity, quantum yield and emission wavelength of these derivatives are reported. Films made from poly(amic acid) with the corresponding chromophore covalently bound show better fluorescence properties than the acid monomer. Copyright *

A novel polyaryloxydiphenylsilane was synthesized successfully by solution polycondensation of 2,2Ј-dimethyl-biphenyl-4,4Ј-diol with diphenyldichlorosilane and the catalyst triethylamine in toluene at 80 °C. Polymers with a relatively high inherent viscosity and yield were obtained when the reaction
