3-trimethyl-3H-indole derivatives created nearinfrared fluorophore Cy5. The synthetic method is air-tolerant, photosensitizer free, metal free, and condensation agent free. Livingcells make Cy5 on a time scale of minutes under white light irradiation at a low power intensity, with the monomer as the only exogenous agent. The new method is promising to find applications in cell studies for in situ spatiotemporally
2,3,3-trimethyl-3 H - indole 衍生物的光活化三聚化产生近红外荧光团 Cy5。该合成方法耐空气、不含光敏剂、不含金属、不含缩合剂。活细胞在低功率强度的白光照射下在几分钟的时间尺度内制造 Cy5,单体作为唯一的外源性试剂。这种新方法有望在活细胞中原位时空控制荧光成像的细胞研究中找到应用。
