EtS(CH2)4SEt, L1, forms with CuI a luminescent 2D polymer [Cu4I4{μ-L1}2]n (CP1), which exhibits no triplet excitation energy migration, but with CuBr, it forms a 3D material (CP2), [(Cu2Br2){μ-L1}]n consisting of parallel (Cu2Br2S2)n layers bridged by L1's. CP2 shows T1–T1 annihilation at 298 K but not at 77 K.
