摘要
We report the expedient synthesis of a series of new "PN-anthracene" derivatives, the naphtho[2,3-e]-1,2-azaphosphorine-2-oxides, which incorporate a variety of 3-aryl substituents. These compounds represent a new class of pi-extended PN-heterocycles, featuring strong UV absorption, emission in the visible range, and Stokes shifts up to 10000 cm(-1). These molecules show alignment of dipoles, strong dimerization through N-H and P=O hydrogen bond donors/acceptors, and efficient aromatic stacking in the solid state.
