Using tetra-kis(2-chloropropionamido) indium(Ⅲ) phthalocyanine chloride [ InClPc( NHCOCH-ClCH3 ) 4 ] as initiator, a novel four-arm star polymethylmethacrylate( PMMA-InClPc) with an indium chloride phthalocyanine core was synthesized by atom transfer radical polymerization( ATRP) method. PMMA-InClPc structure was characterized by Fourier transform infrared ( FTIR) spectroscopy, ultraviolet-visible ( UV-Vis) spectroscopy and hydrogen nuclear magnetic resonance spectroscopy ( 1H NMR ) techniques. The molecular weight and molecular weight distribution of polymer sample were measured by gel permeation chromatograph ( GPC) . Polymerization reaction kinetics of the synthesized polymer was also studied by GPC. The results show that polymerization process follows a first-order reaction kinetics. The third order nonlinear optical properties were measured by the Z-scan technique at 532 nm using a frequency-doubled Q-switching Nd:YAG laser pulse with pulse width of 21 ps. When the molecular weight of polymer is 2902, the third-order nonlinear polarizability X(3) reaches the maximum value, which is 7.216í10-10 esu by calculation. These results display that the synthesized PMMA-InClPc polymer has potential nonlinear optical applications.
