Abstract

Organic color centers (OCCs) are quantum defects synthetically installed on the surface of carbon nanotube semiconductors. The defects act as exciton traps where electrons and holes recombine radiatively to produce single photons in the shortwave infrared, even at room temperature. Unlike native defects, OCCs are molecularly tunable and can be synthetically controlled, potentially with atomic precision, using organic chemistry and physical means. These molecularly tunable defect color centers have opened exciting opportunities for chemistry, physics, materials science, biomedical engineering, and quantum technologies. In this talk, we will discuss our recent progress in this emerging field and provide an outlook on the rapidly expanding research and applications of these synthetic defects. In particular, the emitted photons carry local chemical information at the defect sites, opening new possibilities for pushing the limits of sensing and imaging. Time permitting, we will give examples to illustrate the potential applications of these quantum defects as biochemical sensors.
