Guest‐controlled diastereoselective self‐assembly of a diboryltellurophene and a chiral tetrol bearing an indacene backbone was achieved to give either hetero‐ or homochiral macrocyclic boronic esters, selectively. The heterochiral isomer (hetero‐[2+2] Te ) exhibited a higher inclusion ability for electron‐deficient aromatic guests, leading to effective quenching of phosphorescence from the diboryltellurophene moieties. The reported macrocycles collectively represent a promising arene sensing approach based on phosphorescence.
