A method of making a molecular sieve may include: reacting a source selected from the group consisting of: a source of a tetrahedral element in the presence of a structure directing agent (SDA) selected from the group consisting of: Ar+-L-Ar, Ar+-L-Ar-L-Ar+, Ar+-L-Ar-L- NR3+, and ArAr+-L-Ar+Ar, where Ar+ is to a N-containing cationic aromatic ring, Ar is to a non-charged aromatic ring, L is a methylene chain of 3-6 carbon atoms, NR3+ is to a quaternary ammonium, and ArAr+ and Ar+Ar are a fused aromatic ring structure comprising both a N-containing cationic portion and a non-charged portion, to produce the molecular sieve. |
