英文摘要	the nonlinear absorption properties of two series of novel free base and metalated meso 5,10-a(2)b(2) substituted porphyrins, both bearing p-tolyl as an a substituent and tms-ethynyl or bromine as a b substituent, were investigated with the open z-scan technique at 532 nm in the ns time regime. most of the compounds exhibited a transmission drop with increasing input fluence. this behavior is desirable for their applications in optical limiting. more complex responses: a drop in transmission followed by an increase in transmission or an increase in transmission followed by a transmission drop, with increasing input fluence, were detected for certain compounds. all of the recorded responses were successfully fitted with a four-level model with simultaneous two-photon absorption arising from the higher excited states (consecutive one- + one- + two-photon absorption). the tms-ethynyl group was found to be a more efficient meso substituent in optical limiting than the bromine atom. indium, lead and zinc complexes with tms-ethynyl substituents were the strongest positive nonlinear absorbers amongst compounds studied which makes them the most interesting candidates for optical limiting application.
