Tetrahedral structures comprising Sn-cored materials with five differenttypes of substituents were synthesized. For the substituents, we employedmethyl and tert-butyl as aliphatic groups, and naphthyl and phenyl asaromatic groups. The bandgap is in the range of 3.28 - 3.56 eV. The All thecompounds with substituents showed bathochromical photoluminescencecharacteristics and exhibited aggregation-induced emission characteristics. Specifically, the compounds with aromatic substituents prohibited sidechainpacking and π-π stacking. The energy levels of the highest occupiedand lowest unoccupied molecular orbitals were measured to be 5.5 - 5.75and 2.0 - 2.37 eV, respectively. The maximum luminance efficiencies andpower efficiencies of the Sn-cored compound-based organic light-emittingdiodes (OLEDs) were 0.38 - 0.71 cd/A and 0.15 - 0.28 lm/W. Therefore, it isexpected that Sn-cored compounds with a tetrahedral structure, especiallythose containing aromatic substituents, can be used as an active material inblue OLEDs for prohibiting side-chain packing and π-π stacking.
