本文研究了几种羟基联苯和氨基联苯的激发波长、荧光波长和荧光强度随pH值的变化，以期将所得数据用于生物材料中羟基联苯的测定。2-而3-羟基联苯、2，2-二羟基联苯、2-氨基联苯、3-氨基联苯和4-氨基联苯则表现出激发态电离。4-羟基-和4，4 [图像]-二羟基-联苯没有，并显示正常的荧光随pH值的变化。联苯和2-和4-甲氧基联苯显示荧光在pHO-14范围内没有变化。4，4 [image]-二羟基联苯在适当的pH值下显示出对应于非离子化形式、单阴离子和二阴离子的荧光峰，但2，2 [image]-二羟基联苯显示出对应于非离子化形式和仅单阴离子的荧光峰，表明其不形成二阴离子。3-和4-硝基联苯是非荧光的。这些结果进行了讨论。
The variation with pH of the excitation and fluorescence wavelengths and fluorescence intensity of several hydroxy- and amino-biphenyls has been investigated with a view to using the data for the determination of hydroxybiphenyls in biological material. 2- and 3-Hydroxy-, 2,2[image]-dihydroxy-, and 2- 3- and 4-amino-biphenyl exhibited excited-state ionization. 4-Hydroxy- and 4,4[image]-dihydroxy-biphenyl did not, and showed normal fluorescence changes with pH. Biphenyl and 2- and 4-methoxybiphenyl showed no changes in fluorescence in the range pHO-14. 4,4[image]-Dihydroxyblphenyl showed fluorescent peaks corresponding to the un-ionized form, the monoanion and dianion at the appropriate pH values, but 2,2[image]-dihydroxybiphenyl showed fluorescent peaks corresponding to the un-ionized form and the monoanion only, suggesting that it did not form a dianion. 3- and 4-Nitrobiphenyl were non-fluorescent. These results are discussed.
