Methods: The silver phenylacetylides were analyzed by The method of MALDI-TOF-MS. Results: The main members of The silver phenylacetylide were tetramer and pentamer The degree of polymerization was found to be up to twelve. Conclusion: The polymerization series of The silver phenylacetylide are according to The formula: Mn= nM+ Ag, (n = 1.2.3... ).展开更多
