The molecular structure of -butylphenyl)-1-(4-methoxyphenyl)-1,3-propa
nedione in its crystal state was determined as an enol structure, enyl
)-3-hydroxy-1-(4-methoxyphenyl)-2-propen-1-one (BPMP), C20H22O3, with
a disordered tert-butyl group attached to the benzene ring. BPMP has a
powder second-order harmonic generation (SHG) efficiency ten times th
at of urea.
