溶剂绿 7 用途与合成方法
Pyranine is capable of discriminating ranges of cations from the Cu
+
ion, even in competing environment. Pyranine displays a rapid fluorescence response (t
1/2
=1.66 min) towards the Cu
+
ion, and the micromolar detection limit enables the detection of the ion in environmental samples. The observed stoichiometry of complexation between Pyranine and Cu
+
is 2:1.
The pH-sensitive fluorescent indicator Pyranine is studied to determine its usefulness as probes for the living cornea and anterior chamber. Adequate concentrations are reached in the cornea and anterior chamber after topical administration; measurements can be made by fluorophotometry for many hours. The pH is calculated by measuring the ratio of fluorescent intensity at two excitation wavelengths, I463/I404, a measurement which is dependent on pH but independent of the concentration of the fluorophore and other variables which can alter the intensity. In the rabbit eye, Pyranine in the cornea and anterior chamber is observed to undergo easily measurable changes in fluorescent ratios associated with lid closure and contact lens wear, indicating its sensitivity to mild changes in pH.

以1,3,6,8-芘四磺酸四钠盐为原料合成溶剂绿7的一般步骤如下：在2000毫升三颈烧瓶中加入1200克浓硫酸，搅拌下加入120克1,3,6,8-芘四磺酸四钠盐，轻微加热以促进完全溶解后，缓慢升温至90°C并维持1小时。反应完成后，用水浴将反应混合物冷却至40°C以下，缓慢滴加480克液体硫磺黑，滴加过程控制在3小时内完成。随后，将反应温度维持在100°C左右继续反应5小时。反应结束后，冷却至室温，将反应混合物倒入720克冰水中，得到粘稠物料，经过滤后干燥滤饼，得到芘四磺酸四钠盐。接下来，将芘四磺酸四钠盐溶于1000毫升水中，转移至2000毫升三口烧瓶中，用氢氧化钠溶液调节至中性，再加入300克片状氢氧化钠。缓慢加热至微沸状态，保持5小时。反应完成后，冷却，先用盐酸调节pH值至7左右，然后加入100克氯化钠搅拌至完全溶解，缓慢沉淀出淡黄色固体。经过滤、干燥，最终得到约245克8-羟基-1,3,6-芘三钠磺酸盐。
