文摘The precise control of multicomponent complex topological configurations integrating more than one compound or one crystal phase with high spatial and angular precision is extremely challenging due to anisotropic noncovalent interaction and undesirable phase separation.Herein,we present a superstacking self-assembly approach via noncovalent interaction strength(|EBGP-TCNB(−3.14 kcal mol−1)|>|EBGP-TFP(−2.84 kcal mol−1)|>|EBGP-OFN(−2.15 kcal mol−1)|>|EBGP(−1.33 kcal mol−1)|)adjustment for the fine synthesis of molecular heterostructures with various photophysical properties and lowdimensional morphologies,as well as phase heterostructures with multifunctional optoelectrical characteristics and multidimensional morphologies.Notably,the anisotropic noncovalent interaction and lattice matching principle facilitate the sequential crystallization and horizontal/longitudinal growth in the crystal-puzzle process,respectively.This super-stacking self-assembly approach is amenable to precise design and fine synthesis of desirable organic multicomponent complex topological configurations for integrated optoelectronics.
