摘要: Abstract The X-ray structures of two benzyl alcohol type biphenyl lignin model molecules 3 and 4 were determined their fluorescence properties established in the crystalline state heptane methanol solutions at 300 K. No phosphorescence emission was observed 77 K contrast to conjugated carbonyl compounds 1 2 . torsion angle fluorophore appeared be main parameter governing solid liquid states.
