摘　　要：Polymorphic structures of cyclometalated cationic Pt(Ⅱ)-isocyanide complexes(-)-1[Pt((−)-NNC)(Dmpi)]Cl with different packing modes can be isolated before.In this paper,a series of solid-state powders with variable colors(yellow,orange and red)have been obtained from the evaporation of complex(-)-1 in different solvents.The crystallinity,thermogravimetric properties,absorption,luminescence and excited state lifetimes have been studied.In addition,intermolecular Pt…Pt interactions in the optimized configurations of different aggregates have been explored,and calculations of frontier molecular orbitals of monomer,dimer,trimer and tetramer have been carried out.

关 键 词：Pt(Ⅱ)complex luminescence Pt…Pt interactions density functional theory(DFT)
