The invention relates to a compound, an organic photoelectric device and electronic equipment. The compound has a structure shown as a formula I in the specification. The compound provided by the invention simultaneously contains adamantane and a group A containing N-hetero, the composition of adamantane is chair-form conformational cyclohexane, and the whole ring system has symmetry and rigiditycharacteristics, which is beneficial to reduce the sublimation temperature and lower the glass-transition temperature; phenanthroline, pyridine, pyrimidine or triazine and the like are excellent electron-deficient planar groups, and the groups enable molecules to tend to be planar and are matched with adamantane, so that stacking and electron coupling of the molecules are facilitated. Therefore, the compound provided by the invention has an appropriate HOMO value and a relatively low LUMO value, can improve the electron injection and transmission capability, has relatively high triplet state energy level ET, high electron mobility, excellent thermal stability and film stability, and is beneficial to improve the device performance.
