alpha-Iminonitriles: Composite Functional Groups for Functionalization of Pyrene
Functionalization of polycyclic aromatic hydrocarbons (PAHs) with functional groups is essential for tuning the optoelectronic properties, solid stacking and solubility. alpha-Iminonitriles are composite functional groups (CFGs) containing imine (C=N-R) and nitrile (CN) moieties with strong electron-withdrawing character and good stability, which could be readily introduced through several effective synthetic methods. alpha-Iminonitriles have been widely used as intermediates for organic transformations but hold untapped potential for modification of organic functional materials. We herein disclose that alpha-iminonitriles are eminent groups for modifying the properties of pyrene. The introduction of alpha-iminonitriles to pyrene causes many changes: significantly lowering the LUMOs, red-shift in absorption and emission spectra, tuning the solid-stacking, triggering aggregation-induced emission and white-light emission. This work indicates that CFGs such as alpha-iminonitriles may provide extra toolkits for the functionalization of organic functional materials which would help to tap the potentials of novel or existed materials.
