Fluorogenic aromatic aldehydes bearing arylethynyl groups were developed. They were used for monitoring the reaction progress of organocatalytic aldol reactions in DMSO through an increase in the fluorescence intensity based on the formation of the florescent aldol product. The ratios of the fluorescence intensities of the aldols to the aldehydes were more than 300. These results suggest that the fluorescence assay system using the aldehyde is useful for the rapid identification of superior aldol catalysts and reaction conditions.

A series of anthracene and perylene bisimide derivatives with electron-withdrawing benzimidazole substituents has been designed and prepared. Detailed studies on the electrochemical and photophysical properties as well as the field-effect mobilities of these new compounds were explored. The incorporation of electron-withdrawing benzimidazole groups lowered the LUMO levels in both anthracene and perylene bisimide derivatives compared to those of the parent compounds. Strong emission was observed for all anthracene derivatives, but only weak emission was observed for perylene bisimide derivatives. The anthracene derivatives showed typical p-type semiconducting character, even when the derivatives were substituted with electron-withdrawing benzimidazole groups at the 9- and 10-positions, which apparently does not lower the LUMO levels to transform them into electron-transporting molecules. Perylene bisimide derivatives displayed typical n-channel semiconducting properties with low threshold voltages and electron mobilities of ca. 5.2 × 10-5 cm2 V-1 s-1. Copyright
