We present a self-assembled template that consists of tetraphenylmethane derivatives and adopts a periodic lateral arrangement on a Au(111) surface with acetyl groups sticking out of the molecular film. By using the tip of a scanning tunneling microscope, these acetyl groups can be removed in a spatially controlled way without significantly affecting the remaining molecular assembly. The chemically modified molecules can be readily distinguished from the original ones such that information can be engraved in the molecular film. Both the modified nature of an individual molecule and the order of the molecular film are shown to persist at room temperature. The mesh size of this molecular graph paper can be tuned by varying the length of the molecular spacer so that writing and reading information on the nanoscale with variable letter sizes becomes possible.

A synthetic approach to dimetalated arenes using flow microreactors and the switchable application to chemoselective cross-coupling reactions

In spite of their potential utility, the chemistry of dimetalated arenes is still in its infancy because they are extremely difficult to synthesize. We report a novel method of synthesizing arenes bearing a boryl group and a metallic substituent, such as boryl, silyl, stannyl, or zincyl groups, in an integrated flow microreactor based on the generation and reactions of aryllithiums bearing a trialkyl borate moiety. The bimetallic arenes showed a remarkable chemoselectivity in palladium-catalyzed cross-coupling reactions. The selectivity was switched by the selection of the metal species that constitutes the dimetalated arenes as well as appropriate catalysts.
Fluorescent chemosensors of carbohydrate triols exhibiting TICT emissions

4-4′-Disubstituted biphenyl boronic acids (BBAs) are push-pull fluorophores with "turn-on" fluorescence properties. Upon carbohydrate triol binding, BBA boronate esters can participate in photon-induced electron transfer, giving a twisted intramolecular charge transfer (TICT) complex. The resulting TICT emissions distinguish between carbohydrates that bind to boron as a diol versus triol unit, thereby revealing stereochemical information about the carbohydrate.

A modular synthesis of functionalised biaryl phenols from two boronic acid derivatives has been developed via one-pot Suzuki-Miyaura cross-coupling, chemoselective control of boron solution speciation to generate a reactive boronic ester in situ, and oxidation. The utility of this method has been further demonstrated by application in the synthesis of drug molecules and components of organic electronics, as well as within iterative cross-coupling.
