Abstract

A novel photochromic system was discovered, in which leucomethylene blue, reduced by l-ascorbic acid, was irradiated with 405 nm visible light, resulting in the solution undergoing a colorless-to-blue transition. The process was then repeated, with the solution returning to its colorless state when left undisturbed. This photochromic reaction is sensitive enough to be driven by a blue-violet LED lamp and enables figures to be drawn in solution with a laser pointer.

摘要

发现了一种新型光致变色体系，其中被L-抗坏血酸还原的无色亚甲基蓝在405 nm可见光照射下，溶液会发生从无色到蓝色的转变。然后重复该过程，溶液在静置时会恢复到无色状态。这种光致变色反应足够灵敏，可由蓝紫色发光二极管灯驱动，并且能用激光笔在溶液中绘制图案。
