摘要：

The two-step method for the synthesis of acyl phosphine oxides from aromatic aldehydes was optimized giving the products in 52-97% overall yield. Linear and nonlinear optical properties of series of acyl-phosphine oxides possessing substituents with different electron-donating ability were investigated. Two-photon absorption cross sections (sigma(2)) of push-pull acyl-phosphine oxide was determined as 9GM via z-scan measurements with femtosecond,laser pulses. Using acyl-phosphine oxides possessing dipolar structure as initiators, 3D nanopatterns were successfully fabricated by two-photon initiated polymerization. These compounds also initiate classical photopolymerization when excited with UV radiation.
