The zeolite UTD-1 may be formed under hydrothermal synthesis conditions using a directing agent that does not include a metal atom therein. Methods for synthesizing the zeolite UTD-1 may comprise: combining at least a silicon atom source and a directing agent having a structure of in an aqueous medium; forming the zeolite in the aqueous medium under hydrothermal synthesis conditions, such that the zeolite has a framework silicate with a cationic portion of the directing agent occluded within pores or channels of the framework silicate; and isolating the zeolite from the aqueous medium. The zeolite has a powder x-ray diffraction pattern with at least the following 2θscattering angles: 6.0±0.12, 7.6±0.1, 14.66±0.15, 19.7±0.15, 21.27±0.15, 22.13±0.15, 22.61±0.15, and 24.42±0.10 for a borosilicate form zeolite, or 6.0±0.12, 7.6±0.15, 14.55±0.15, 19.64±0.15, 21.01±0.20, 21.90±0.20, 22.34±0.20, and 24.38±0.20 for an aluminosilicate form zeolite.
