摘 要:以對硝基苯甲醛和吡咯為原料,硝基苯為溶劑,反應合成了四(4-硝基苯基)卟啉(TNPP),將TNPP用二氯化錫還原后得到了四(4-氨基苯基)卟啉(TAPP),并進(jìn)一步用TAPP與金屬鹽反應合成了其金屬配合物。利用紫外可見(jiàn)光譜、紅外光譜、核磁共振氫譜對合成產(chǎn)物進(jìn)行了結構表征。并研究了這些卟啉化合物在不同外加電場(chǎng)條件下的表面光電壓譜(SPS),結果表明,TAPP及其金屬配合物都具有良好的光電性能,且其Soret 帶與Q 帶的光伏響應強度隨外加正電場(chǎng)光伏響應強度的增加而增強,隨外加負電場(chǎng)光伏響應強度的增加而減弱,具有P-型半導體的特征。 |

Abstract:Tetra(4-nitrophenyl) porphyrin (TNPP) was synthesized in nitrobenzene,using 4-nitro- benzaldehyde and pyrrole as starting materials . Tetra(4-aminophenyl)porphyrin(TAPP) was synthesized by the reduction of TNPP with SnCl2/HCl. Then metallo-porphyrin complexes were synthesized from TAPP and metal salts. The products were characterized by UV-vis,IR and 1H NMR spectrum. The surface photovoltage of the products were studied by surface photovoltage spectra (SPS) in different electric fields. It was shown that TAPP and its metalloporphyrin complexes all had good photoconductivity. The surface photovoltage response in tensity of Soret band and Q band were enhanced with an external positive electric field and weakened with a negative electric field,and possessed the characteristic of p-type semiconductor. |
Key words:tetra(4-aminophenyl)porphyrin;metalloporphyrin complexes;surface photovoltage spectra |
