摘要

我们首次合成了一个负光致变色二甲基二氢芘磷酸盐（DHPPs）库，该库可以在所谓的“生物窗口”中以定量的方式被红光和远红光（高达740 nm）光子激活。这种特殊类型的有趣特征是它们在全水介质中的响应速度非常快，并且开环量子产率有所提高。此外，这种反转可以在可见光（蓝光）下激活，也可以在热条件下以定量的方式激活，从而实现有效的双向可见光介导开关，使这种特殊类型的光开关在生物领域的潜在应用更具吸引力。此外，传统的未取代DHPP和我们改进的DHPP的混合物的全光子正交光开关展示了多功能分子逻辑操作的演示。

Installation of Cationic Phosphorous on Dimethyldihydropyrene Photoswitches: Expanding the Atomic Repertoire towards Far-Red Photoswitching in Water

We have synthesized for the first time, a library of negative photochromic dimethyldihydropyrene phosphonium salts (DHPPs) that can be activated by red and far-red (up to 740 nm) photons in a quantitative manner in the so-called “biological window." The intriguing feature of this particular class is their remarkably fast response in fully aqueous media with an improved ring-opening quantum yield. Additionally, the reversal can be activated upon visible (blue) light and also under thermal conditions in a quantitative manner, achieving efficient bidirectional visible light-mediated switching rendering this particular class of photoswitches even more attractive towards their potential application in biological premises. Additionally, all-photonic orthogonal photoswitching of a mixture of conventional unsubstituted DHP and one of our modified DHPP showcases the demonstration of multifunctional molecular logic operations.

期刊介绍： Chemical Science is a journal that encompasses various disciplines within the chemical sciences. Its scope includes publishing ground-breaking research with significant implications for its respective field, as well as appealing to a wider audience in related areas. To be considered for publication, articles must showcase innovative and original advances in their field of study and be presented in a manner that is understandable to scientists from diverse backgrounds. However, the journal generally does not publish highly specialized research.
