RAS question
The method to design and synthesise MOFs with precise pore sizes, developed by Omar Yaghi, is called:
Correct answer: (B) Reticular chemistry.
Omar Yaghi's method for designing and synthesising metal-organic frameworks with precise, predetermined pore sizes is called reticular chemistry.
Explanation
Reticular chemistry links molecular building blocks by strong bonds into crystalline, extended structures, and the UC Berkeley College of Chemistry treats porous MOFs as a central example. Yaghi's approach is not a loose discovery of a material, but a design method for building frameworks whose pore sizes and chemical properties can be set in advance. Once the building blocks and pores are controlled, scientists can tailor MOFs for tasks such as water harvesting and carbon capture. The named method behind precise MOF design is reticular chemistry.
Why the other options are wrong
- (A) Combinatorial chemistry is not the method named by the UC Berkeley College of Chemistry; Yaghi's MOF precision is linked to reticular chemistry, the building-block approach behind these porous frameworks.
- (C) Supramolecular chemistry covers a broader field, while the UC Berkeley College of Chemistry specifically names reticular chemistry as the precision method used for MOF and COF structures.
- (D) Green chemistry focuses on reducing environmental harm in chemical design and use; water harvesting and carbon capture are applications of MOFs tailored through reticular chemistry, not the name of Yaghi's method.
Concept
Materials chemistry within Science & Technology often links a new material to its scientist, design method, and application. RAS-style science coverage treats MOFs through Yaghi, reticular chemistry, and uses such as water harvesting and carbon capture, not just through the application alone.
