report the synthesis of cocrystals of a substituted benzoxazole
and catechol from a primary amine and 3,5-di-tert-butylbenzoquinone. Fourier transform infrared and NMR spectroscopy
studies revealed that cocrystals 2 could be synthesized
in excellent yield from 1 and 3,5-di-tert-butylbenzoquinone. Introduction of an amine into the cocrystal structure
enhanced the CO2 adsorption capacity of the cocrystals
at room temperature from 15.69 to 44.21 mg/g. Our results indicated
the ability to use cocrystals for CO2 capture and to easily
modify them to enhance their CO2 adsorption capacity.
