  5,12-二氢苯并[b]吩嗪的波长选择性光活化自催化氧化及其在无金属合成中的应用

  摘要：

  用中心发射波长在 365 至 595 nm 范围内的 LED 研究了 5,12-二氢苯并[ b ]吩嗪 (DHBP) 的光化学稳定性。在高达 516 nm 的波长下观察到DHBP 到苯并[ b ]吩嗪 (BP) 的光化学转化。DHBP 不吸收 490 和 516 nm 的光，但证实了 DHBP 光活化自催化氧化为具有这些波长的 BP。反应速率在 111–208 μg min -1范围内使用这些 LED。对反应机理进行了研究，实验结果排除了分子间相互作用，例如福斯特共振能量转移、分子间电荷转移、光致电子转移和激子复合物的形成。用电子顺磁共振验证了活性氧的形成，这表明其在合成中的潜力。当使用太阳光作为光源时，1 mg mL -1 DHBP的氧化速率为393 μg min -1。在类似化合物上也观察到相同的自催化氧化，它可用于生产用于半导体的无金属有机物质。

  An improved electrochromic device, the device incorporating an electrochromic medium that comprises at least three electroactive materials having absorption spectra that add together such that the color of the electrochromic medium can be pre-selected by individually choosing the concentrations of the at least three electroactive materials. The electrochromic medium generally maintains the pre-selected perceived color throughout its normal range of voltages when used in an electrochromic device. The at least three electroactive materials include at least one electrochemically reducible material (cathodic material), at least one electrochemically oxidizable material (anodic material) and at least one additional electroactive material which may be either an anodic or cathodic material. Thus, there are always three electroactive materials present in the medium, with at least two either being anodic or cathodic materials. The pre-selected color may be chosen from a wide variety of colors and may be, for example, red, orange, yellow, green, blue, purple. For electrochromic mirrors for motor vehicles, a presently preferred color is gray.

  一种改进的电致变色装置，该装置包括一种电致变色介质，该介质包含至少三种吸收光谱相加的电活性材料，因此可以通过单独选择至少三种电活性材料的浓度来预先选择电致变色介质的颜色。当在电致变色装置中使用时，该电致变色介质通常在其正常电压范围内保持预先选择的感知颜色。至少三种电活性材料包括至少一种电化学可还原材料（阴极材料），至少一种电化学可氧化材料（阳极材料）和至少一种附加电活性材料，该附加电活性材料可以是阳极或阴极材料。因此，介质中始终存在三种电活性材料，其中至少有两种为阳极或阴极材料。可以从各种各样的颜色中选择预先选择的颜色，例如红色、橙色、黄色、绿色、蓝色、紫色。对于机动车的电致变色镜子，目前首选的颜色是灰色。
