Caffeine is known to form c omplexes by self - association and with other organic compounds. Its biological activity in changing the effects of neurotoxins has been attributed to its f ormation of stacked complexes. Charge - transfer complexes of c affeine have also been reported. However, complexes reported are stoichiometric and exhib it color only in solution.
