Synthesis, optical characterization and crystal and molecular X-ray structure of a phenylazojulolidine derivative

摘要: Abstract The synthesis, spectroscopic characterization, and X-ray crystal structure of [4-(2,3,6,7-tetrahydro-1H,5H-pyrido[3,2,1-ij]quinolin-9-ylazo)-phenyl]-methanol azodye are reported. A 37–47 nm bathochromic shift has been observed by comparison with analogous azodyes where diethylamino or dimethylamino groups act as donor moiety in agreement the larger electronic donating properties julolidine. azobenzene skeleton adopts a planar trans-configuration intra- inter-molecular hydrogen bonds have detected. correlation between molecular features attempted.
