A method of making a molecular sieve may include reacting a source selected from tetrahedral element sources in the presence of a structure directing agent (SDA) selected from Ar +-L-Ar, Ar +-L-Ar-L-Ar +, Ar +-L-Ar-L-NR < 3 + >, and ArAr +-L-Ar + Ar, to produce a molecular sieve, where Ar + is a cationic aromatic ring containing N, Ar is an uncharged aromatic ring, L is a methylene chain of 3 to 6 carbon atoms, NR < 3 + > is a quaternary ammonium, and ArAr + and Ar + Ar are fused aromatic ring structures comprising both an N-containing cationic moiety and an uncharged moiety. 分子筛的制造方法可以包括：使选自四面体元素源的源在选自Ar+-L-Ar、Ar+-L-Ar-L-Ar+、Ar+-L-Ar-L-NR3+和ArAr+-L-Ar+Ar的结构导向剂(SDA)的存在下反应，以产生分子筛，其中Ar+是含N的阳离子芳族环，Ar是不带电荷的芳族环，L是3-6个碳原子的亚甲基链，NR3+是季铵，并且ArAr+和Ar+Ar是包含含N阳离子部分和不带电荷部分二者的稠合芳族环结构。
