General description

4-(Dimethylamino)benzonitrile is extensively used in photophysical studies due to its ability to undergo intramolecular charge transfer (ICT) from the dimethylamino moiety to the cyanophenyl moiety on photo-excitation leading to the appearance of dual fluorescence.

Application

4-(Dimethylamino)benzonitrile can be used in the synthesis of 3,6-diphenyl-2,5-dihydro-pyrrolo[3,4-c]pyrrole-1,4-dione derivatives.

Universal adhesives use a combined primer/bonding resin applied either in 2-step etch-and-rinse (2-E&R) or 1-step self-etch (1-SE) mode. This study investigated whether three universal adhesives would benefit from an extra bonding layer (EBL), essentially making them 3-step E&R (3-E&R) and
