## Abstract Summary: The high‐molecular‐weight functional polyacetylene that contain a __para__‐aminoazobenzene chromophore, poly[2‐{N‐Methyl‐N‐(4‐(4‐ethynylphenylazo)phenyl)amino}ethyl butyrate] [poly(EAPAB)], was synthesized in moderate yield and characterized by FT‐IR, ^1^H NMR, UV‐vis, TGA, and
Cyanation of bis(4,5-dicyano-l-methyl-2-imidazolyl)arnine(1) using cyanogen chloride gave N,N-bis(4,5-dicyano-l-methyl-2-imidazolyl)cyanamide(3) as a light yellow solid. Compound 3 is themmlly labile and upon heating the N-CN bond is cleaved and the reactive amine intermediate readily reacts with th
