Chiral emissive porous organic cages
WebIntroduction Shape-persistent organic cages opened up new possibilities to form various supramolecular hosts and porous materials with well-defined, tunable internal cavities. 1 The porosity of organic cages originates from the presence of the internal cavity, which is responsible for the intrinsic porosity of the material along with other accessible pores that … WebA pair of chiral, emissive and porous tubular multi-functional organic molecular cages were synthesized easily by imine chemistry of 4,4',4'',4'''-(ethene-1,1,2,2-tetrayl)-tetrabenzaldehyde (ETTBA) with ( R , R )- or ( S , S )-diaminocyclohexane (CHDA). It was found that the chirality of CHDA was transferred and amplified to tetraphenylethylene ...
