A photoconjugation strategy based on light‐triggered Diels–Alder addition of o‐quinodimethanes is compatible with biomolecules and proceeds rapidly at ambient temperature without the need of a catalyst. Spatial control was confirmed by photopatterning of a small‐molecule ATRP initiator, a polymer, and a peptide in a time‐of‐flight secondary‐ion mass spectrometry investigation.
基于光激发的Diels-Alder添加邻喹啉甲烷的光结合策略与生物分子兼容,并且在环境温度下无需催化剂即可快速进行。在飞行时间二次离子质谱研究中,对小分子ATRP引发剂,聚合物和肽进行了光图案化,从而确认了空间控制。
