Raman modes of the new processable polymer poly(2,3-alkyl-thieno[3,4-b]-pyrazine) with a bandgap about 0.9 eV were measured and calculated. spectroscopy revealed two strong lines at 1520 cm−1 1560 in CC stretching mode region. By changing exciting laser line these exhibit dispersion 16 25 cm−1/eV, respectively. Calculations on ground state that quinonoid structure is by 13 kcal/mol per repeat unit more stable than aromatic form. using scaled quantum mechanical oligomer force field method we...

Thiosemicarbazones continue to attract the interest of researchers as potential anticancer drugs. For example, 3-aminopyridine-2-carboxaldehyde thiosemicarbazone, or triapine, is most well-known representative this class compounds that has entered multiple phase I and II clinical trials. Two new triapine derivatives HL1 HL2 were prepared by condensation reactions 2-pyridinamidrazone S-methylisothiosemicarbazidium chloride with 3-N-(tert-butyloxycarbonyl) amino-pyridine-2-carboxaldehyde,...
