| Abstract: | Two new porphyrins 2,8,12,18\|tetraethyl\|3, 7,13,17\|tetramethyl\|5,15\|dithiophenylporphyrin (7a) and 5,15\|dibithiophenyl\|2,8,12,18\|tetraethyl\|3,7,13,17\|tetramethyl\|porphyrin (7b) are synthesized in high yields (45.1% and 61.2% respectively) through the reaction of dipyrrolemehane and thiophenylaldehyde or bithiophenylaldehyde. At the same time the porphyrinogens of these porphyrins can also be getted in high yields (81.3% and 64.7%) from this reaction without adding oxydant. Fluorescent properties of them have been studied. Their maximum fluorescent emissions are both at 631 nm and their quantum yields are 4.1% (7a) and 1.4% (7b) respectively. Spectrums of UV\|Vis fluorescence and H 1 NMR show that with the increment of the substituents in the meso\|positions of porphyrin, the porphyrin's cyclic plane become more nonplanar. |
