The first quadrupolar 8-dimethylaminoquinoline-derived 6-(8-DMAQ-OAc)2 (1c) and 5-(8-DMAQ-OAc)2 (2c) photosensitive probes underwent photolysis under UV (365 nm) and NIR (730 nm two-photon (TP)) irradiation conditions, showing Qu = 9.3% and 6.6% quantum yields and δu = 0.07 GM and 0.40 GM uncaging cross-sections, respectively.

systematic SAR study of a “caging” group showed a strong influence of the position of the donor dimethylamino group on the efficiency of photolysis of the DMAQ (2-hydroxymethylene-(N,N-dimethylamino)quinoline) caged acetate under one-photon near-UV or two-photon near-IR excitation. Photorelease of l-glutamate by the most efficient 8-DMAQ derivative strongly and efficiently activated glutamate receptors

High two-photon photolysis cross sections and water solubility of probes are important to avoid toxicity in biomedical applications of photolysis. Systematic variation of the position of a carboxyl electron-withdrawing group (EWG) on photolysis of 8-dimethylaminoquinoline protecting groups identified the C5-substituted isomer as a privileged dipole. The 5-benzoyl-8-DMAQ substitution yields a caging
高的双光子光解截面和探针的水溶性对于避免光解在生物医学应用中的毒性很重要。在对8-二甲基氨基喹啉保护基进行光解时,羧基吸电子基团(EWG)位置的系统变化将C5取代的异构体确定为优先偶极子。的5-苯甲酰基-8- DMAQ替代产生一个封闭基团具有增强的双光子解笼锁的横截面(δ û = 2.0 GM)和良好的水溶解度(ç ≤50毫米,pH值7.4)中。
