Recommanded Product: 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane. The article was titled ãCompact Conjugated Polymer Dots with Covalently Incorporated Metalloporphyrins for Hypoxia Bioimagingã? The information in the text is summarized as follows:
Hypoxia is closely related to multiple diseases, especially in tumors, which increases the aggressiveness and drug resistance of cancer cells. Precise hypoxia imaging is of great significance for cancer diagnosis and the evaluation of therapeutic effects. A kind of hydrophobic polymer (i.e., PFPtTFPP) as an imaging probe for hypoxia with fluorene as an energy donor and an oxygen-sensitive PtII porphyrin as an energy acceptor was developed. Compact polymer dots (Pdots) with a small size were prepared by nanopptn. The PFPtTFPP Pdots showed excellent hypoxia sensing in solution with high sensitivity and full reversibility. The emission intensity, quantum yields, lifetime, and single-particle brightness significantly increased under hypoxia conditions. Remarkably, hypoxia imaging in vitro and in vivo was realized, and a clear increase in brightness was observed under hypoxia conditions and in the tumor area. Excellent hypoxia imaging ability is beneficial to potential applications in cancer diagnosis. In the experiment, the researchers used many compounds, for example, 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6Recommanded Product: 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane)
4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane(cas: 24388-23-6) can be used as a substrate in the study of Suzuki–Miyaura coupling of various aryl iodides over SiliaCat Pd(0).Recommanded Product: 4,4,5,5-Tetramethyl-2-phenyl-1,3,2-dioxaborolane
