| 摘 要： | 近年来,出于节约一次性能源的考虑,人们已经加大对太阳能等天然资源的利用,致力于模拟天然光合作用的研究1￣3],而光合作用中的捕光复合物又称为光子天线。光子天线中往往存在一种或几种猝灭剂,猝灭剂吸收光子后产生激发态的能量可以在不同分子或者同一分子的不同生色团之间转移,转移出能量的一方为能量给体,另一方为能量受体。 |

| Abstract: | A modified zirconium phosphate (abbreviated as DAZrP) composite with a large interlayer spacing was prepared. Then DAZrP was mixed with an organic chromophore, tetraphenylporphine(TPP) solution. The interlayer spacings and the optical properties of the samples before and after the interaction of TPP and DAZrP were characterized by X-ray diffraction (XRD), fourier transform infrared (FTIR) spectroscopy, ultraviolet-visible (UV-Vis) spectroscopy and fluorescence spectroscopy. The results manifested that the interlayer spacing of DAZrP was 3.56 nm, and a new lamellar structure corresponding to the d-spacing of 3.11 nm was observed after TPP mixed with DAZrP, indicating the intercalation between TPP and DAZrP. After the TPP chromophore was bound to DAZrP, the characteristic fluorescence intensity of the suspension was evidently increased compared with that of TPP solution (at the same concentration), which results from the difference in micro-environment for TPP in DAZrP and in aqueous solution. |
