  • Patent number: 11342517
    Abstract: A dibenzoheterocyclic compound having a structure shown in a formula wherein the dibenzoheterocyclic compound has a low LUMO energy level and can be matched with an electron transport material favorable for injection and transport of electrons. The dibenzoheterocyclic compound has hole transport performance. As a light-emitting layer material, the dibenzoheterocyclic compound balances the ratio of electrons to holes in a light-emitting layer increasing the combination probability and improving the light-emitting efficiency of a device. The spatial configuration of the dibenzoheterocyclic compound avoids stacking of material molecules, avoiding generation of high energy excitons due to energy transfer among molecules, reducing annihilation of excitons, and inhibiting efficiency roll-off. The dibenzoheterocyclic compound has thermal stability, so blue light can be emitted efficiently and stably.

  • Patent number: 11203707
    Abstract: The present invention relates to a cold-crystallizing material having high latent heat, and a method of using the present material for heat storing. The material of the invention comprises of a phase change material and an additive which is preferably a hydrophilic polymer matrix. Preferably, sugar alcohols, such as erythritol or D-mannitol, are used as the phase change material. The polymer of the invention is preferably cross-linked and ionic, i.e. a polyelectrolyte. PCM stores a high amount of heat energy while melting and releases the stored thermal energy by cold-crystallization. Compared to previously studied cold-crystallizing materials, the latent heat of the cold-crystallizing material of the invention is considerably higher, and cold-crystallization is more repeatable in successive melting-crystallization cycles. The material can be used for heat storing. Heat energy can be released from the material by a heat pulse on demand. The method is particularly suitable for long-term heat storing.
