Suzuki–Miyaura cross‐coupling reactions have been utilized for the derivatization of the upper‐rim of cavitands, but unfortunately, only a relatively small number of suitable, inexpensive boronic acids are available. Herein, we report the synthesis and structure determination of a tetraboronic pinacolyl ester functionalized cavitand, which has been successfully employed in high‐yielding coupling reactions with iodoarenes covering a range of functional groups, thereby demonstrating the versatility and chemoselectivity of this platform.

The liquid-phase lasers may be designed to give a continuous wave output beam or a pulsed emission, depending on the form of the optical excitation of the organic dye solution. The simplicity and versatility makes the liquid dye-laser technology attractive for many applications, other attributes are its very spectral emission capability, including simultaneous multi-colour emission.
