Abstract: An organic optoelectronic device comprises a first electrode, an active layer and a second electrode. An active layer material of the active layer comprises a near-infrared organic small molecule with vinyl groups which includes a structure of formula I: Wherein o and p are independently selected from any integer from 0 to 2, and o+p>0. Ar1 is an electron-withdrawing group with a unilateral fused ring structure. Ar2 is a monocyclic or polycyclic structure containing ketone and an electron-withdrawing group, and has a double bond to bond other groups. R1 is different from R2. The active layer material of the organic optoelectronic device comprises an organic small molecule with an asymmetric carbon chain, and has adjustable material solubility, arrangement and conductivity. The present invention also provides an active layer material comprising organic small molecules with asymmetric carbon chains and with symmetrical carbon chains independently, which improve production efficiency.
