| 中文摘要 | the three-photon absorption effect (3pa) of two novel symmetrical charge transfer fluorene-based molecules (abbreviated as basf and bmosf) has been determined by using a q-switched nd:yag laser pumped with 38 ps pulses at 1064 nm in dmf. the measured 3pa cross-sections are 84 x 10(-78) and 114 x 10(-78) cm(6) s(2), respectively. the geometries and electronic excitations of these two molecules are systematically studied by pm3 and zindo/s methods. the relationships between 3pa cross-sections and intramolecular charge transfer are discussed micromechanically. the experimental and theoretical results have shown that the larger intramolecular charge transfer, which was characterized by the charge density difference between the ground state (so) and the first excited state (s-i), the greater enhancement of the 3pa cross-sections.
