摘要：

Three-photon absorption (3PA) properties of symmetric-type carbazole derivatives show great potential for application in light-activated therapy and optical limiting. A novel symmetrical carbazole derivative (abbreviated as POCP) with end-groups of 1,10-phenanthroline rings as the donor moieties, chained via carbonnitrogen (C?=?N) double bond, has been synthetized and its three photon absorption properties has been also determined by using a Q-switched Nd: YAG laser pumped with 30?ps pulses at 1064?nm in dimethylformamide. The measurement of 3PA cross-section of this compound is performed by open aperture Z-scan and s3PA is 481?X?1078?cm6 s2/photon2 for the transition S0???S1. The influence of the molecular structure of this compound on three-photon absorption cross-sections is discussed micromechanically by Austin model 1 and Zerner's Intermediate Neglect of Differential Overlap/S method.
