[2.2]Paracyclophane-Substituted Triarylboranes Featuring Temperature-Sensitive Dual Fluorescence and Circularly Polarized Luminescence
New types of triarylborane compounds <b>(</b><i><b>S</b></i><sub><b>p</b></sub><b>)-MCp</b>, <b>(</b><i><b>S</b></i><sub><b>p</b></sub>,<i><b>S</b></i><sub><b>p</b></sub><b>)-BCp</b>, and <b>(</b><i><b>S</b></i><sub><b>p</b></sub>,<i><b>S</b></i><sub><b>p</b></sub>,<i><b>S</b></i><sub><b>p</b></sub><b>)-TCp</b> containing one to three (<i>S</i><sub>p</sub>)-4-dimethylamino [2.2]paracyclophane units at different phenyl rings of triarylborane were disclosed. These molecules exhibited obvious well-separated temperature-sensitive dual fluorescence characteristics in THF, which is promising and challenging for small organic luminescent molecules. In addition, they displayed intensive circularly polarized luminescence (CPL) signals with a luminescence dissymmetry factor (|<i>g</i><sub>lum</sub>|) that reached 10<sup>-3</sup>.
