摘要：
In this paper the intramolecular/intermolecular excimer formations of [Fe-2(bpmp)(1-pyace)(2)](BF4)(2) [ZnFe(bpmp)(1-pyace)(2)](ClO4)(2) and [Zn-2(bpmp)(1-pyace)(2)]ClO4 which contain 1-pyreneacetic acid as a chromophore are reported. The fluorescent properties of the ZnZn complex offer the intramolecular dimers of the two chromophores in addition to intermolecular dimers due to the intermolecular stacking. The ZnFe and FeFe complexes are under the strong influence of quenching and show weak intramolecular/intermolecular excimer formation in the concentration more than 10(-4) M. The emission intensities and intensity ratios (I-E/I-M) of the fluorescence are dependent on the metal ions.
