Zhu, Zhaoyang; Zhang, Xue; Guo, Xing; Wu, Qinghua; Li, Zhongxin; Yu, Changjiang; Hao, Erhong; Jiao, Lijuan; Zhao, Jianzhang published an article in 2021. The article was titled 《Orthogonally aligned cyclic BODIPY arrays with long-lived triplet excited states as efficient heavy-atom-free photosensitizers》, and you may find the article in Chemical Science.Synthetic Route of C7H9BO3 The information in the text is summarized as follows:
In photosensitizers, long triplet excited state lifetimes are key to their efficient electron transfer or energy transfer processes. Herein, we report a novel class of cyclic trimeric BODIPY arrays which were efficiently generated from easily accessible meso-mesityldipyrrinone and arylboronic acids in one pot. Arylboronic acid, for the first time, was used to provide a boron source for BODIPY derivatives Due to the well-defined and orthogonally aligned BODIPY cores as verified by X-ray crystallog., these BODIPY arrays show strong exciton coupling effects and efficient intersystem crossings, and are novel heavy-atom-free photosensitizers with a long-lived triplet excited state (lifetime up to 257.5 μs) and good reactive oxygen species generation efficiency (up to 0.72) contributed by both 1O2 and O2- under light irradiation The experimental part of the paper was very detailed, including the reaction process of 3-Methoxyphenylboronic acid(cas: 10365-98-7Synthetic Route of C7H9BO3)
3-Methoxyphenylboronic acid(cas: 10365-98-7) belongs to boronic acids. Boronic acids are mild Lewis acids which are generally stable and easy to handle, making them important to organic synthesis.Synthetic Route of C7H9BO3
