Interestingly , the Zn ( HQLG ) 2 gels showed obviously different fluorescent color with respect to ( R , R ) - and ( S , S ) - 1 , 2 - diaminocyclohexane , thus providing visible chiral recognition via the naked eye .
 Chemical: Zn ( HQLG ) 2; Chemical: ( R , R ) - and ( S , S ) - 1 , 2 - diaminocyclohexane
