摘要:
1,3-Connected polyarylmethanes were synthesized using repetitive additions of aryllithiums to carbonyl compounds. The polyarylmethanes with molecular mass up to 2900 amu were purified by chromatography and characterized using FABMS, NMR, and elemental analyses. FABMS and 2D COSY NMR were found particularly useful in characterization of large polyarylmethanes.
