  Confused porphyrinoids have received much attention attribute to their flexible structure,novel reactivity,various coordination chemistry and charming optical properties[1].Neo-confused smaragdyrin BF2 complex 1 and doubly neo-confused smaragdyrin BF2 complex 2 were prepared by SNAr reaction[2] of dibromodipyrrin BF2 complex with N-confused tripyrranes.Protonation of 3 and 4 gave dication species 3H2 2+and 4H2 2+,respectively(Scheme 1).[3] These porpyrin analogues and their derivative were characterized with 1H NMR,UV/Vis absorption spectra and single crystal X-ray diffraction analysis.Further exploration of their photophysical properties and aromaticity are ongoing in our laboratory.
