The development of optoelectronics technology greatly contributes to our daily life and industrial evolution. In particular, two-dimensional (2D) materials with ultrathin structure have received worldwide research interests in the field of optoelectronics mainly owing to the intrinsic electronic and optical attributes. The on-going researches indicate that electrically conducting MOF and COF demonstrate distinctive properties and promising surface functionality, while their inherent band structure and electronic features can be rationally controlled by structural modification. With rapid development of 2D materials-based optoelectronic devices, the utilization of 2D polymer MOF and COF semiconductors has become a new tendency to meet the scope of adaptive, low-cost, and flexible device fabrication. In this review, the recent research activities on 2D MOF and COF materials are provided. The fabrication and semiconducting properties of 2D MOF and COF materials have been explained. Apart from that, both advantages and limitations of the newly developed 2D MOF and COF materials regarding their potential in optoelectronic devices have been discussed. Additionally, different types of 2D MOF and COF materials and performance adjusting strategies have been systematically summarized. Furthermore, the remaining challenges and current prospects of applying 2D MOF and COF into optical-to-electrical and electrical-to-optical conversion devices have been introduced.
