Tejerina, Lara published the artcileOne-Pot Synthesis of π-Extended Fluorenone-Fused Subphthalocyanines, Category: nitriles-buliding-blocks, the main research area is fluorenone fused Subphthalocyanine.
A family of inherently chiral nonplanar aromatic chromophores, comprising Subphthalocyanines bearing fluorenone-fused units (SubFcs), were prepared by an innovative one-pot synthesis, which relies on the standard cross-cyclotrimerization of phthalonitriles followed by intramol. Friedel-Crafts acylation. Their Q-band absorption experiences a ca. 20 nm red shift per fused fluorenone as a consequence of the enlarged conjugated π-system.
Organic Letters published new progress about Chromophores. 91-15-6 belongs to class nitriles-buliding-blocks, name is Phthalonitrile, and the molecular formula is C8H4N2, Category: nitriles-buliding-blocks.
