摘要

利用插入化学法

将金属卟啉配合物四苯基卟啉合银(Ⅱ)

组装到改性磷酸锆(十二烷基三甲基铵磷酸锆) 无机层状物中。配合物与改性磷酸锆作用后

层状框架的层间距由3.00 nm调整到1.96 nm

卟啉的Soret吸收带和发射光谱都出现明显的位移

其中最大吸收由421 nm红移到429 nm

最大发射由651 nm红移到655 nm。尤其是揷层组装悬浮液的荧光强度同金属卟啉的水溶液相比大大增强

当配合物浓度为4 molL

-1

时

荧光强度增加了几乎10倍。这种改性磷酸锆作为框架有助于提高金属卟啉配合物的荧光性能。

Abstract

The optical properties of porphyrins have been extensively investigated in the fields of labels

catalysts and sensors

which are attributed to the absorbance in the near ultraviolet and visible region and emission in the red light region. In general

porphyrins present weak luminescence in aqueous media. Especially

the emission of metal phorphyrin shows much weaker. Therefore

it is a challenging task to enhance the emission of the metal complex in aqueous system. In this paper

the optical properties of metalloporphyrin complex

silver (Ⅱ) tetra-phenyl porphyrin

(TPP-Ag)

intercalated into an inorganic lamellar framework (dodecyltrimethylammomium zirconium phosphate

DTZrP) was studied. It was attempted to optimize the optical property resorting to the special microenvironment provided by DTZrP. The DTZrP lamellar framework was prepared by lyophilization method

and the result of X-ray powder diffraction demonstrates that the interval of the lamellar framework is about 3.00 nm. The metalloporphyrin TPP-Ag was synthesized according to previous procedure and characterized with FTIR

UV-visible

and elementary analysis. By means of intercalation chemistry

the TPP-Ag chromophore was assembled into DTZrP successfully. The optical behavior of the chromophore takes on evident change. The Soret absorption peak is red-shifted from 421 nm in the aqueous solution to 429 nm in the suspension. Most of all

the fluorescence property of TPP-Ag assembled into lamellar framework is improved dramatically compared to the chromophore in the aqueous solution. The fluorescence intensity is enhanced by nearly 10-fold. It is concluded that the lamellar framework DTZrP provides appropriate setting which can improve effectively the optical behavior. The optimized fluorescence property is in favor of the chromophore as fluorescence probe in the body of organism.
