      An unusual negative 1H NMR chemical shift of methyl group in condensation product of isocopalane diterpenoid with p-toluenesulfonyl hydrazide was discovered. 2D NMR, computational studies and single-crystal X-ray diffraction analysis were used to determine the real confirmation.

    2. Changing to Poly(rod-coil) Polymers: a Promising Way for an Optoelectronic Compound to Improve Its Film Formation

      Small molecular optoelectronic compound [BDT(DTBT)2 formed poor films on the substrates of glass and ITO glass. Such situation has been changed when it was changed into poly(rod-coil) polymers, which can improve its film formation capability as well as retaining the basic optoelectronic properties.
