The present invention provides a method of cleaving labile functional groups from molecules by exposure to electromagnetic radiation in which the molecules are contacted with a chemical compound whose triplet state is energetically higher than the triplet state of the labile functional group and are then exposed to electromagnetic radiation, with the labile functional group and the suitable chemical compound having different absorption maxima for electromagnetic radiation. Further, the invention provides a method of manufacturing DNA chips by spatially addressed, light-controlled nucleotide synthesis on solid substrates. In addition, the present invention provides a chemical composition comprising a molecule with a labile functional group and a chemical compound whose triplet state is higher than the triplet state of the labile functional group, with the labile functional group and the chemical compound having different absorption maxima for electromagnetic radiation, and describes the use of the chemical composition in the manufacture of DNA chips.
本发明提供了一种通过暴露于电磁辐射来裂解分子中的易损官能团的方法,在该方法中,分子与三重态能量高于易损官能团的三重态的化合物接触,然后暴露于电磁辐射,易损官能团和合适的化合物对电磁辐射具有不同的吸收最大值。此外,本发明还提供了一种通过在固体基底上进行空间寻址、光控核苷酸合成来制造 DNA 芯片的方法。此外,本发明还提供了一种化学组合物,该化学组合物包括具有易变官能团的分子和三重态高于易变官能团三重态的化合物,易变官能团和化合物对电磁辐射具有不同的吸收最大值,并描述了该化学组合物在制造 DNA 芯片中的用途。

An expeditious, solvent-free procedure for the conversion of the xanthine bases theophylline, 8-methyltheophylline, caffeine, and theobromine to the corresponding 6-thio and 2,6-dithio derivatives using Lawesson's reagent under microwave irradiation is proposed.
